Port C – Functionality and Structure
Port C can be configured to perform one or more
of the following functions (see Figure 56):
I
MCU I/O Mode
I
CPLD Output – McellBC7-McellBC0 outputs
can be connected to Port B or Port C.
I
CPLD Input – via the Input Macrocells (IMC)
I
In-System Programming (ISP) – JTAG pins
(TMS, TCK, TDI, TDO) are dedicated pins for
device programming. (See the section entitled
“PROGRAMMING IN-CIRCUIT USING THE
JTAG SERIAL INTERFACE,” page 121, for
more information on JTAG programming.)
I
Open Drain – Port C pins can be configured in
Open Drain Mode
I
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.
