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.
Read strobe output pin for the data bus. This function is enabled
when the external bus is enabled.
Data sample input pin for input capture ICU5
General purpose I/O. The register can be set to select whether to
use a pull-up resistor. This function is enabled either in single-chip
mode or with the WR/WRL pin output disabled.
Write strobe output pin for the data bus. This function is enabled
when both the external bus and the WR/WRL pin output are en-
abled. WRL is used to write-strobe 8 lower bits of the data bus in
16-bit access while WR is used to write-strobe 8 bits of the data
bus in 8-bit access.
RX input pin for CAN2 Interface (EVA devices)
External interrupt request input pin for INT10
General purpose I/O. The register can be set to select whether to
use a pull-up resistor.This function is enabled either in single-chip
mode or with the WRH pin output disabled.
Write strobe output pin for the 8 higher bits of the data bus. This
function is enabled when the external bus is enabled, when the
external bus 16-bit mode is selected, and when the WRH output
pin is enabled.
TX Output pin for CAN2 (EVA devices)
General purpose I/O. The register can be set to select whether to
use a pull-up resistor. This function is enabled either in single-chip
mode or with the hold function disabled.
Hold request input pin. This function is enabled when both the ex-
ternal bus and the hold function are enabled.
Waveform output pin for output compare OCU4
General purpose I/O. The register can be set to select whether to
use a pull-up resistor. This function is enabled either in single-chip
mode or with the hold function disabled.
Hold acknowledge output pin. This function is enabled when both
the external bus and the hold function are enabled.
Waveform output pin for output compare OCU6
General purpose I/O. The register can be set to select whether to
use a pull-up resistor. This function is enabled either in single-chip
mode or with the external ready function disabled.
Ready input pin. This function is enabled when both the
external bus and the external ready function are enabled.
