PSB 21473
Parallel Ports
9.1
PORT0
The two 8-bit ports P0H and P0L represent the higher and lower part of PORT0,
respectively. Both halfs of PORT0 can be written (eg. via a PEC transfer) without
effecting the other half.
If this port is used for general purpose IO, the direction of each line can be configured
via the corresponding direction registers DP0H and DP0L.
Each port line of P0L and P0H can be switched into push/pull or open drain mode via the
open drain control register ODP0H.
An internal pull transistor is connected to the pad if bits of register P0xPUDEN = ’1’, no
matter whether the INCA-D is in normal operation mode or in power down mode. Either
pulldown transistor or pullup transistor will be selected via P0xPUDSEL.
The output driver is disabled in power down mode unless P0xPHEN = ’1’.
After reset all bits of P0xPUDEN and P0xPUDSEL are set to ’1’ except P0LPUDSEL.6
and P0HPUDSEL.2.
While this feature allows to start without any external pull device, the configuration may
be overwritten by external pull devices. In this case the internal pull resistors should be
disabled by software after reset.
