I
(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).

P35
I
(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
I
(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
I
(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.
16

P40
H
(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).

19
P41
G
(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).
