Data Sheet
8.5
If this 5-bit port is used for general purpose I/O, the direction of each line can be
configured via the corresponding direction register DP4.
Each port line can be switched into push/pull or open drain mode via the open drain
control register ODP4.
For port pins configured as input (via DP4 or alternate function), an internal pull transistor
is connected to the pad if register P4PUDEN = ’1’, no matter wheter the C161U is in
normal operation mode or in power down mode. Either pulldown transistor or pullup
transistor will be selected via P4PUDSEL.
For port pins configured as output, the internal pull transistors are always disabled. The
output driver is disabled in power down mode unless P4PHEN = ’1’.
After reset, P4PUDEN and P4PUDSEL are set to LOW signal.
