I/O

Port 70: I/O port (High current output available)

P70

WAIT

Input

WAIT: Pin used to request CPU bus wait (It is active in (1

+ N) waits mode.

Set by the bus-width/wait control register.)

P71

I/O

Port 71: I/O port (high current output available)

NMI

Input

Non-maskable interrupt request pin: Interrupt request pin with

falling edge. Can also be operated at falling and

rising edges by program.

CLK

Output

Clock output: Outputs “fSYS ÷ 2” clock.

Pulled up during reset.

Can be disabled for reducing noise.

Input

“1” should be inputted with TMP93CS32.

AM8/

Input

Address mode: Selects external data bus width.

“1” should be inputted. The data bus width for external access is set by chip

select/wait control register, port 1 control register.

ALE

Output

Address latch enable

Can be disabled for reducing noise.

RESET

Input

Reset: Initializes TMP93CS32. (with pull-up resistor)

VREFH

Input

Pin for high level reference voltage input to AD converter

VREFL

Input

Pin for low level reference voltage input to AD converter

AVCC

Input

Power supply pin for AD converter

AVSS

Input

GND pin for AD converter (0 V)

Input

Oscillator connecting pin

Output

Oscillator connecting pin

VCC

Input

Power supply pin

VSS

Input

GND pin (All VSS pins are connected to the GND (0 V).)

Note:

Built-in pull-up resistors can be released from the pins other than the RESET pin by software.
