Function

LQFP*1

QFP*2

P33

(STBC)

General-purpose I/O port

Functions as the WRH pin in 16-bit external bus mode if the

WRE bit in the ECSR register is “1”.

WRH

Functions as the upper data write strobe output (WRH).

P34

(STBC)

General-purpose I/O port

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

in the ECSR register is “1”.

HRQ

Functions as the hold request input pin (HRQ).

P35

(STBC)

General-purpose I/O port

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

the ECSR register is “1”.

HAK

Functions as the hold acknowledge output (HAK) pin.

P36

(STBC)

General-purpose I/O port

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

the ECSR register is “1”.

RDY

Functions as the external ready input (RDY) pin.

P37

(STBC)

General-purpose I/O port

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

the ECSR register is “1”.

CLK

Functions as the machine cycle clock output (CLK) pin.

P40

(STBC)

General-purpose I/O port

When UART0 is operating, the data at the pin is used as the

serial input (SIN0).

Can be set as an open-drain output port (OD40 = “1”) by the

open-drain control register (ODR4).

The setting does not apply for ports set as inputs (D40 = “0”:

invalid at the input setting).

SIN0

Functions as the UART0 serial input (SIN0).

P41

(STBC)

General-purpose I/O port

Functions as the SOT0 pin if the SOE bit in the UMC register is

“1”.

Can be set as an open-drain output port (OD41 = “1”) by the

open-drain control register (ODR4).

The setting does not apply for ports set as inputs (D41 = “0”:

invalid at the input setting).

SOT0

Functions as the UART0 serial data output pin (SOT0).
