The state of port C at reset is mode dependent. In single-chip or
bootstrap modes, port C pins (PC[7:0]) are high-impedance inputs.
Writes to DDRC can change any of the bits to outputs. In expanded or
test modes, port C pins provide the data lines (DATA[7:0]) for external
memory devices. The MCU’s internal data bus can also be driven on port
C by setting the IRVNE bit in the system configuration options register
(OPT2). See
When port C functions as GPIO (single-chip mode), it can be configured
for wired-OR operation by setting the CWOM bit in the OPT2 register.
This disables port C’s P-channel drivers, effectively generating
open-drain-type outputs. To output a logic 0 on a wired-OR pin, the MCU
turns on its N-channel driver. To generate a logic 1, both P- and
N-channel drivers are turned off, presenting a high-impedance state
which requires an external pullup resistor to apply the appropriate
voltage level.
