12 - PARALLEL PORTS
Port 5 pins have a special port structure (see Figure 35), first because it is an input only port, and second
because the analog input channels are directly connected to the pins rather than to the input latches.
Figure 35 : Block Diagram of a Port 5 Pin
12.8.2 - Port 5 Schmitt Trigger Analog Inputs
A Schmitt trigger protection can be activated on each pin of Port 5 by setting the dedicated bit of register
P5DIDIS.
P5DIDIS (FFA4h / D2h)
12.9 - Port 6
If this 8-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.

Port 5 Digital Disable Register Bit y
P5DIDIS.y = 0: Port line P5.y digital input is enabled (Schmitt trigger enabled)
P5DIDIS.y = 1: Port line P5.y digital input is disabled (Schmitt trigger disabled,
necessary for input leakage current reduction)
