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”.
Functions as the upper data write strobe output (WRH).
General-purpose I/O port
Functions as the HRQ pin in external bus mode if the HDE bit
in the ECSR register is “1”.
Functions as the hold request input pin (HRQ).
General-purpose I/O port
Functions as the HAK pin in external bus mode if the HDE bit in
the ECSR register is “1”.
Functions as the hold acknowledge output (HAK) pin.
General-purpose I/O port
Functions as the RDY pin in external bus mode if the RYE bit in
the ECSR register is “1”.
Functions as the external ready input (RDY) pin.
General-purpose I/O port
Functions as the CLK pin in external bus mode if the CKE bit in
the ECSR register is “1”.
Functions as the machine cycle clock output (CLK) pin.
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).
Functions as the UART0 serial input (SIN0).
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).
Functions as the UART0 serial data output pin (SOT0).
