Port 5 is an 8-bit input-only port with Schmitt-Trigger charact.
The pins of Port 5 also serve as analog input channels for the
A/D converter, or they serve as timer inputs:

AN4,
T2EUD GPT1 Timer T2 Ext. Up/Down Ctrl. Inp.
AN5,
T4EUD GPT1 Timer T4 Ext. Up/Down Ctrl. Inp.
AN6,
T2IN
GPT1 Timer T2 Input for
Count/Gate/Reload/Capture
AN7,
T4IN
GPT1 Timer T4 Input for
Count/Gate/Reload/Capture
IO
Port 3 is a 9-bit bidirectional I/O port. It is bit-wise
programmable for input or output via direction bits. For a pin
configured as input, the output driver is put into high-
impedance state. Port 3 outputs can be configured as push/
pull or open drain drivers. The input threshold of Port 3 is
selectable (TTL or special).
The following Port 3 pins also serve for alternate functions:
T3EUD
GPT1 Timer T3 External Up/Down Control Input
T3IN
GPT1 Timer T3 Count/Gate Input
MRST
SSC Master-Receive/Slave-Transmit Inp./Outp.
MTSR
