P45
G
General-purpose I/O port
This function is valid when the corresponding bit of the upper
address control register specification is “port”.
External address bus output pin of the bit 21
This function is valid when the corresponding bit of the upper
address control register specification is “address”.
16-bit input capture #0 data input pin
During 16-bit input capture #0 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.
16-bit timer #0 data input pin
During 16-bit timer #0 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.
General-purpose I/O port
This function is valid when the corresponding bit of the upper
address control register specification is “port”.
External address bus output pin of the bit 22
This function is valid when the corresponding bit of the upper
address control register specification is “address”.
16-bit input capture #1 data input pin
During 16-bit input capture #1 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.
16-bit timer #1 data input pin
During 16-bit timer #1 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.
General-purpose I/O port
This function is valid when the corresponding bit of the upper
address control register specification is “port”.
External address bus output pin for the bit 23
This function is valid when the corresponding bit of the upper
address control register specification is “address”.
16-bit input capture #2 data input pin
During 16-bit input capture #2 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.
16-bit timer #2 data input pin
During 16-bit timer #2 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.
