Operation Timing
4-Bit Bus Mode (BS = GND)
Figure 4 shows 4-bit data latch timing when SHL = GND, that is, the
EIO2
pin is a chip enable input and
EIO1
pin is a chip enable output. When SHL = V
CC
, the
EIO1
pin is a chip enable input and
EIO2
pin is a
chip enable input.
When a low chip enable signal is input via the
EIO1
pin, the HD66120T is first released from data standby
state, and, at the falling edge of the following CL2 pulse, it is released entirely from standby state and starts
latching data. It simultaneously latches 4 bits of data at the falling edge of each CL2 pulse. When it has
latched 236 bits of data, it sets the
EIO2
signal low. When it has latched 240 bits of data, it automatically
stops and enters standby state, initiating the next HD66120T, as long as its
EIO2
pin is connected to the
EIO1
pin of the next HD66120T.
The HD66120Ts output one line of data from the Y1–Y240 pins at the falling edge of each CL1 pulse. Data
d1 is output from Y1, and d240 from Y240 when SHL = GND, and d1 is output from Y240, and d240 from
Y1 when SHL = V
CC
. Data output level is either VLCD, V2, V3, or V4 depending on the combination of
the M signal and the data level.
