# 10 ?e 17 10.display control instruction the display control instructions control the internal state of the ks0108b. instruction is received from mpu to ks0108b for the display control. the following table shows various instructions instruction d/i r/ w db7 db6 db5 db4 db3 db2 db1 db0 function display on/off 0 0 0 0 1 1 1 1 1 0/1 controls the display on or off. internal status and display ram data are not affected. 0:off, 1:on set address 0 0 0 1 y address (0~63) sets the y address in the y address counter. set page (x address) 0 0 1 0 1 1 1 page (0 ~7) sets the x address at the x address register. display start line 0 0 1 1 display start line(0~63) indicates the display data ram displayed at the top of the screen. status read 0 1 b u s y 0 on/ off r e s e t 0 0 0 0 read status. busy 0:ready 1:in operation on/off 0:display on 1:display off reset 0:normal 1:reset write display data 1 0 display data writes data (db0:7)into display data ram. after writing instruction, y address is increased by 1 automatically. read display data 1 1 display data reads data (db0:7) from display data ram to the data bus. free datasheet http:///
# 11 ?e 17 11.detailed explanation display on/off the display data appears when d is and disappears when d is 0. though the data is not on the screen with d = 0, it remains in the display data ram. therefore, you can make it appear by changing d = 0 into d = 1. display start line z address aaaaaa ( binary ) of the display data ram is set in the display start line register and displayed at the top of the screen. figure 2. shows examples of display ( 1/64 duty cycle ) when the start line = 0-3. when the display duty cycle is 1/64 or more ( ex. 1/32, 1/24 etc. ), the data of total line number of lcd screen, from the line specified by display start line instruction, is displayed set page ( x address ) x address aaa ( binary ) of the display data ram is set in the x address register. after that, writing or reading to or from mpu is executed in this specified page until the next page is set. see figure 1. r/w d/i db7 db6 db5 db4 db3 db2 db1 db0 0 0 0 0 1 1 1 1 1 d r/w d/i db7 db6 db5 db4 db3 db2 db1 db0 0 0 1 1 a a a a a a r/w d/i db7 db6 db5 db4 db3 db2 db1 db0 0 0 1 0 1 1 1 a a a free datasheet http:///
# 12 ?e 17 set y address y address aaaaaa ( binary ) of the display data ram is set in the y address counter. after that, y address counter is increased by 1 every time the data is written or read to or from mpu. status read busy when busy is 1, the lsi is executing internal operations. no instruction are accepted while busy is 1, so you should make sure that busy is 0 before writing the next instruction. on/off shows the liquid crystal display condition: on condition or off condition. when on/off is 1, the display is in off condition. when on/off is 0, the display is in on condition reset reset = 1 shows that the system is being initialized. in this condition, no instructions except status read can be accepted. reset = 0 shows that initializing has system is in the usual operation condition. write display data r/w d/i db7 db6 db5 db4 db3 db2 db1 db0 0 0 0 1 a a a a a a r/w d/i db7 db6 db5 db4 db3 db2 db1 db0 0 1 busy 0 on/off reset 0 0 0 0 r/w d/i db7 db6 db5 db4 db3 db2 db1 db0 0 0 d d d d d d d d free datasheet http:///
# 13 ?e 17 writes 8-bit data dddddddd ( binary ) into the display data ram. the y address is increased by 1 automatically. read display data reads out 8-bit data dddddddd ( binary ) from the display data ram. then y address is increased by 1 automatically. one dummy read is necessary right after the address setting. for details, refer to the explanation of output register in ?function of each block?. r/w d/i db7 db6 db5 db4 db3 db2 db1 db0 1 1 d d d d 1 d d d 0 12 61 62 63 db0 to db7 to db7 db0 db7 db0 to to db7 db0 x = 0 x = 1 x = 6 x = 7 y a ddress page 0 page 1 page 6 page 7 figure 1. free datasheet http:///
