General-Purpose I/O Ports. The GPIO
registers are accessible by the core for read,
write and configuration. Each of these GPIO
signals can be individually configured to be
input or output. The pins may be used as GPIO
or assigned to their respective alternate
functions. See Section 2.4 on page 54 for
assignment of GPIO pins to alternate functions.
See Section 4.5 on page 113 for further details
on the GPIO pins and their functionality.
General-Purpose Output Port IOPC0. IOPC0
is are targeted for use as power supply control
for the power supply unit. It is accessible by the
core for write and configuration. On V
Up reset, the default state TRI-STATE; it is not
affected by other types of reset. See Section 4.5
on page 113 for further details on these GPIO
pins and their functionality.
