General-purpose I/O port
This function is valid when the ready function is disabled.
Ready input pin
This function is valid when the ready function is enabled.
General-purpose I/O port
This function is valid when the hold function is disabled.
Hold acknowledge output pin
This function is valid when the hold function is enabled.
General-purpose I/O port
This function is valid when the hold function is disabled.
Hold request input pin
This function is valid and when the hold function is enabled.
General-purpose I/O port
This function is valid in external bus 8-bit mode, or when WRH
pin output is disabled.
Write strobe output pin for the upper 8 bits of the data bus
This function is valid in modes where the external bus
16-bit mode is enabled, and WRH pin output is enabled.
Write enable input pin
This function is valid in the flash memory mode.
General-purpose I/O port
This function is valid when WRL pin output is disabled.
Write strobe output pin for the lower 8 bits of the data bus
This function is valid WRL pin output is enabled.
Output enable input pin for each operation command
This function is valid in the flash memory mode.
General-purpose I/O port
Read strobe output pin for the data bus
Chip enable input pin for each operation command
This function is valid in the flash memory mode.
General-purpose I/O port
16-bit input capture #3 data input pin
During 16-bit input capture #3 input operations, these inputs
may be used at any time; therefore, it is necessary to stop
output by other functions on this pin, except when using them
for output deliberately.
DTP/external interrupt #3 data input pin
During DTP/external interrupt #3 input operations, these inputs
may be used at any time; therefore, it is necessary to stop
output by other functions on this pin, except when using them
for output deliberately.
Byte access control input pin
This function is valid in the flash memory mode.
