type

Function

QFP*1

LQFP*2

P34

(CMOS/H)

General-purpose I/O port

Functions as the HRQ pin in external bus mode if the HDE bit in the

EPCR register is “1”.

HRQ

Functions as the hold request input pin (HRQ) in external bus mode.

P35

(CMOS/H)

General-purpose I/O port

Functions as the HAK pin in external bus mode if the HDE bit in the

EPCR register is “1”.

HAK

Functions as the hold acknowledge output pin (HAK) in external bus

mode.

P36

(CMOS/H)

General-purpose I/O port

Functions as the RDY pin in external bus mode if the RYE bit in the

EPCR register is “1”.

RDY

Functions as the external ready input pin (RDY) in external bus mode.

P37

(CMOS/H)

General-purpose I/O port

Functions as the CLK pin in external bus mode if the CKE bit in the

EPCR register is “1”.

CLK

Functions as the machine cycle clock output pin (CLK) in external bus

mode.

P40

(CMOS/H)

General-purpose I/O port.

This pin serves as an open-drain output port with OD40 in the open-

drain control setting register (ODR4) set to “1”. [The pin is disabled

with the input setting (DDR4 register: D40=“0”).]

SIN0

UART0 serial data input (SIN0) pin.

When UART0 is operating for input, this input is used as required and

thus the output from any other function to the pin must be off unless

used intentionally.

P41

(CMOS/H)

General-purpose I/O port.

This pin serves as an open-drain output port with OD41 in the open-

drain control setting register (ODR4) set to “1”. [The pin is disabled

with the input setting (DDR4 register: D41=“0”).]

SOT0

UART0 serial data output pin (SOT0).

This pin is enabled with the UART0 serial data output enabled.

P42

(CMOS/H)

General-purpose I/O port.

This pin serves as an open-drain output port with OD42 in the open-

drain control setting register (ODR4) set to “1”. [The pin is disabled

with the input setting (DDR4 register: D42=“0”).]

SCK0

UART0 serial clock I/O pin (SCK0).

This pin is enabled with the UART0 clock output enabled.
