Port C – Functionality and Structure
Port C can be configured to perform one or more
of the following functions (see Figure
66
):
MCU I/O Mode
CPLD Output – McellBC7-McellBC0 outputs
can be connected to Port B or Port C.
CPLD Input – via the Input Macrocells (IMC)
In-System Programming (ISP) – JTAG pins
(TMS, TCK, TDI, TDO) are dedicated pins for
device programming. (See
PROGRAMMING
IN-CIRCUIT USING THE JTAG SERIAL
INTERFACE, page 134
, for more information
on JTAG programming.)
Open Drain – Port C pins can be configured in
Open Drain Mode
Battery Backup features – PC2 can be
configured for a battery input supply, Voltage
Stand-by (V
STBY
).
PC4 can be configured as a Battery-on
Indicator (V
BATON
), indicating when V
CC
is
less than V
BAT
.
Port C does not support Address Out Mode, and
therefore no Control Register is required.
