General purpose I/O. The register can be set to select whether
to use a pull-up resistor. This function is enabled in single-chip
mode.
I/O pins for 8 lower bits of the external address/data bus.
This function is enabled when the external bus is enabled.
External interrupt request input pins for INT8 to INT15.
General purpose I/O. The register can be set to select whether
to use a pull-up resistor. This function is enabled in single-chip
mode.
I/O pin for bit 8 of the external address/data bus.
This function is enabled when the external bus is enabled.
Event input pin for the reload timer 1
General purpose I/O. The register can be set to select whether
to use a pull-up resistor. This function is enabled in single-chip
mode.
I/O pin for bit 9 of the external address/data bus.
This function is enabled when the external bus is enabled.
Output pin for the reload timer 1
General purpose I/O. The register can be set to select whether
to use a pull-up resistor. This function is enabled in single-chip
mode.
I/O pin for bit 10 of the external address/data bus.
This function is enabled when the external bus is enabled.
Serial data input pin for UART3
Sub external interrupt request input pin for INT11
General purpose I/O. The register can be set to select whether
to use a pull-up resistor. This function is enabled in single-chip
mode.
I/O pin for bit 11 of the external address/data bus.
This function is enabled when the external bus is enabled.
Serial data output pin for UART3
General purpose I/O. The register can be set to select whether
to use a pull-up resistor. This function is enabled in single-chip
mode.
I/O pin for bit 12 of the external address/data bus.
This function is enabled when the external bus is enabled.
