7.5 Port C
Port C is an 8-bit bidirectional port. The port C data register is at $0002
and the data direction register (DDR) is at $0006. The contents of the
port C data register are indeterminate at initial powerup and must be
initialized by user software. Reset does not affect the data registers, but
clears the data direction registers, thereby returning the ports to inputs.
Writing a one to a DDR bit sets the corresponding port bit to output
mode. PC7 has a high current sink and source capability.
Figure 7-1
is
also applicable to port C.
7.6 Port D
Port D is a 7-bit bidirectional port. Four of its pins are shared with the SPI
subsystem and two more are shared with the SCI subsystem. The port
D data register is at $0003 and the data direction register is at $0007.
The contents of the port D data register are indeterminate at initial
powerup and must be initialized by user software. During reset all seven
bits become valid input ports because the DDR bits are cleared and the
special function output drivers associated with the SCI and SPI
subsystems are disabled, thereby returning the ports to inputs. Writing a
one to a DDR bit sets the corresponding port bit to output mode.
