Pin Names and Functions (2 of 6)

Pin name

Number

of pins

Input or

output

Function

P43

Input/output

Port 43: Input/output port (with pull-up)

CS3

Output

Chip select 3: "0" is output if the address is in a designated address area.

KEY27

Input

KEY on wake up input 27: (Dynamic pull up is selectable)

Input with Schmitt trigger

with Noise filter

P44

Input/output

Port 44: Input/output port (with pull-up)

SCOUT

Output

System clock output: Selectable between high- and low-speed clock outputs, as in the case of

CPU

P45

Input/output

Port 45: Input/output port (with pull-up)

BUSMD

Input

Pin for setting an external bus mode: This pin functions as a multiplexed bus by sampling the

"H (DVCC3) level" at the rise of a reset signal. It also functions as a separate bus by sampling

"L" at the rise of a reset signal. When performing a reset operation, pull it up or down

according to a bus mode to be used. Input with Schmitt trigger.

(After a reset operation is performed, it can be used as a port.)

P46

Input/output

Port 46: Input/output port (with pull-up)

ENDIAN

Input

This pin is used to set a mode. It performs a big-endian operation by sampling the "H

(DVCC3) level" at the rise of a reset signal, and performs a little-endian operation by sampling

"L" at the rise of a reset signal. When performing a reset operation, pull it up or down

according to the type of endian to be used.

(After a reset operation is performed, it can be used as a port.) Input with Schmitt trigger

P47

Input/output

Port 47: Input/output port (with pull-up)

TBFOUT

Output

16-bit timer F output: Pin for outputting a 16-bit timer F

P50-P53

Input/output

Port 5: Input/output port (with pull-up) that allows input/output to be set in units of bits

A0-A3

Output

Address: Address buses 0 to 3 (separate bus mode)

INTC-INTF

Input

Interrupt request pins C to F: Selectable between "H" level, "L" level, rising edge, and falling

edge

Input pin with Schmitt trigger
