FUNCTIONAL DESCRIPTION

Microcontroller Interface

The microcontroller interface includes two interface circuits, parallel interface and serial interface.

The statuses of each pin both in parallel interface mode and in serial interface mode are shown below.

SERIAL = “L”

Parallel I/O interface

D7 (I/O)

D6 (I/O)

D5 (I/O)

D4 (I/O)

D3 (I/O)

D2 (I/O)

Data I/O pins

D1 (I/O)

D0 (I/O)

SD (I)

SI (I)

SO (O)

UD (I)

SR3 (O)

SR2 (O)

SR1 (O)

SR0 (O)

SERIAL = “H”

Serial I/O interface

Serial data input pin

Serial clock input pin

Serial data output pin

Select pin for channel statuses output via SR3 to SR0

Channel 1 is output when UD is 0 and channel 5

when UD is 1.

Channel 2 is output when UD is 0 and channel 6

when UD is 1.

Channel 3 is output when UD is 0 and channel 7

when UD is 1.

Channel 4 is output when UD is 0 and channel 8

when UD is 1.
