Section 8 I/O Ports
8.14.6
Port C and port D have an on-chip input pull-up MOS function that can be controlled by software.
This input pull-up MOS function can be switched on or off on a bit-by-bit basis.
Table 8.9 is a summary of the input pull-up MOS states.
Table 8.9
Mode
1 to 3
Legend:
Off:
On/Off: On when PCDDR = 0 and PCODR = 1 (PDDDR = 0 and PDODR = 1); otherwise off.
8.15
Port E and port F are two sets of 8-bit I/O ports. The pins of ports E and F have the same functions
in all operating modes.
