If this 10-bit port is used for general purpose I/O, the direction of each line can be
configured via the corresponding direction register DP3. Each port lines can be switched
into push/pull or open drain mode via the open drain control register ODP3.
Note: Due to pin limitations register bit P3.0..P3.2, P3.4, P3.7 and P3.14 is not
For port pins configured as input (via DP3 or alternate function), an internal pull transistor
is connected to the pad if register P3PUDEN = ’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 P3PUDSEL.
For port pins configured as output, the internal pull transistors are always disabled. The
output driver is disabled in power down mode unless P3PHEN = ’1’.
After reset, P3PUDEN and P3PUDSEL are set to LOW signal.
