5.5 Settings of Port Mode Register and Output Latch When Using Alternate Function

Jul 15, 2010
Port operations differ depending on whether the input or output mode is set, as shown below.
To use the alternate function of a port pin, set the port mode register and output latch as shown in Table 5-6.
Remark The port pins mounted depend on the product. See Table 5-3. Port Functions.
A value is written to the output latch by a transfer instruction, and the output latch contents are output from the pin.
Once data is written to the output latch, it is retained until data is written to the output latch again.
The data of the output latch is cleared when a reset signal is generated.
A value is written to the output latch by a transfer instruction, but since the output buffer is off, the pin status does not
change.
Once data is written to the output latch, it is retained until data is written to the output latch again.
The data of the output latch is cleared when a reset signal is generated.
The output latch contents are read by a transfer instruction. The output latch contents do not change.
The pin status is read by a transfer instruction. The output latch contents do not change.
An operation is performed on the output latch contents, and the result is written to the output latch. The output latch
contents are output from the pins.
Once data is written to the output latch, it is retained until data is written to the output latch again.
The data of the output latch is cleared when a reset signal is generated.
The pin level is read and an operation is performed on its contents. The result of the operation is written to the output
latch, but since the output buffer is off, the pin status does not change.
The data of the output latch is cleared when a reset signal is generated.
