DDC[7:0] — Data Direction for Port C Bits
CWOM — Port C Wired-OR Mode Bit
IRVNE — Internal Read Visibility/Not E Bit
IRVNE can be written only once after reset. The default value of IRVNE
after reset is low.

In expanded modes, setting this bit drives MCU’s internal data bus on
port C.
In single-chip modes, setting this bit inhibits the E clock driver, and the
E pin is pulled low

For More Information On This Product,
0 = Input
1 = Output
0 = Port C operates normally.
1 = Port C outputs are open drain.
0 = No internal read visibility on external data bus
1 = Data from internal reads is driven on port C.
0 = E clock drives the E pin.
1 = E pin is driven low.
