C161U
Parallel Ports
8.6
PORT6
If this 7-bit port is used for general purpose I/O, the direction of each line can be
configured via the corresponding direction register DP6. Each port line can be switched
into push/pull or open drain mode via the open drain control register ODP6.
For port pins configured as input (via DP6 or alternate function), an internal pull transistor
is connected to the pad if register P6PUDEN = ’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 P6PUDSEL.
For port pins configured as output, the internal pull transistors are always disabled. The
output driver is disabled in power down mode unless P6PHEN = ’1’.
After reset, P6PUDEN and P6PUDSEL are set to LOW signal.
