Data Sheet
Figure 9-4
For external memory access the direction of the port pin and the loading of data into the
port output latch are controlled by the bus controller hardware. The input of the port
output latch is disconnected from the internal bus and is switched to the line labeled
“Alternate Data Output” via a multiplexer. The alternate data can be the 16-bit
intrasegment address or the 8/16-bit data information. The incoming data on PORT0 is
read on the line “Alternate Data Input”. The user software should not write to the port
output latch, otherwise unpredictable results may occur. Figure 9-4 shows the structure
of a PORT0 pin.
9.2
The two 8-bit ports P1H and P1L represent the higher and lower part of PORT1,
respectively. Both halfs of PORT1 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 DP1H and DP1L.
Each port line can be switched into push/pull or open drain mode via the open drain
control register ODP1L and ODP1H.
An internal pull transistor is connected to the pad if bits of register P1xPUDEN.y = ’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 P1xPUDSEL.
The output driver is disabled in power down mode unless P1xPHEN = ’1’.
After reset, the bits of P1xPUDEN and P1xPUDSEL are set to ’1’.
