AT83C26
The SC2_FULL bit must be set to use CC42 and CC82.
The CIOn output pin is driven by CARDIOn bit values or by I/O1, I/O2, AUX1 or AUX2 signals.
This selection depends of the IODISn bit value. If IODISn is reset, data are bidirectional between
the I/O1, I/O2, AUX1, AUX2 pins (see IO_SELECT register) and CIOn pins.
Two modes are available on CIOn, CC4n, CC8n signals:
•
•
According to IO_SELECT register value and IODISn bits values, one of 4 input pins (IO1, IO2,
AUX1 or AUX2) is linked to the selected output.
The idle state is the high level. Each signal is bidirectional.
