DATA 2
Serial Data Transmit.
In an alternate mode of operation, this pin is used for data transmit from
MT9094. In the default mode, serial data transmit and receive are performed on the DATA 1 pin
and DATA 2 is tri-stated.
15
DATA 1
Bidirectional Serial Data.
Port for microprocessor serial data transfer compatible with
MCS-51 standard (default mode). In an alternate mode of operation , this pin becomes the data
receive pin only and data transmit is performed on the DATA 2 pin. Input level TTL compatible.
16
CS
Chip Select (Input).
This input signal is used to select the device for microport data transfers.
Active low. (TTL level compatible.)
17
WD
Watchdog (Output).
Watchdog timer output. Active high.
18

S1-S12
Segment Drivers (Output).
12 independently controlled, two level, LCD segment drivers. An
in-phase signal, with respect to the BP pin, produces a non-energized LCD segment. An
out-of-phase signal, with respect to the BP pin, energizes its respective LCD segment.
Digital Ground.
Nominally 0 volts.
