User’s Manual 24-251 V2.0, 2007-07
GPTA, V2.0
The interconnections between the GPTA0/GPTA1/LTCA2 modules and the port I/O lines
are controlled in the port logics. The following port control operations selections must be
executed:
Input/output function selection (IOCR registers)
Pad driver characteristics selection for outputs (PDR registers)
24.6.3.2 Input/Output Function Selection
The port input/output control registers contain bit fields that select the digital output and
input driver characteristics such as port direction (input/output), pull-up/down device or
open-drain selection for outputs, and alternate output selections. The I/O lines for the
GPTA0/GPTA1/LTCA2 modules are controlled by the port input/output control registers
for Port 2, Port 3, Port 4, Port 8, and Port 9. Each of the input/output control registers
controls four port lines using a 4-bit wide bit field PCx (definitions see Table 24-25).
Table 24-24 shows which of the input/output control register bit field is related to a
specific GPTA0/GPTA1/LTCA2 module I/O line. Note that input P2.9/IN1 has special
connections (see Page 24-263).
