Semiconductor
If CPU power down mode (PD, HPD) is activated with this bit set to "1", the
outputs from ports 0, 1, 2, and 3 are switched to floating status.
When this bit is "0", ports 0, 1, 2, and 3 are in output mode.

Timer/counters 0 and 1 are connected serially to from a 32-bit timer/counter
when this bit is set to "1".
TF1 of TCON is set if a carry is generated in the 32-bit timer/counter.
IOCON.6
T32
Leave this bit at "0".
IOCON.7

Port 1 becomes a high impedance input port when this bit is "1".
Port 2 becomes a high impedance input port when this bit is "1".
Port 3 becomes a high impedance input port when this bit is "1".
The 10 kW pull-up resistor for ports 1, 2, and 3 is switched off when this bit
is "1", leaving only the 100 kW pull-up resistor.
Serial port reception error flag.
This flag is set to "1" if an overrun or framing error is generated when data is
received at a serial port.
The flag is reset by software.
