Description
PDR1 stores output data for port 1 pins.
If PDR1 is read while PCR1 bits are set to 1, the value
stored in PDR1 are read. If PDR1 is read while PCR1
bits are cleared to 0, the pin states are read regardless
of the value stored in PDR1.
Bit 3 is a reserved bit. This bit is always read as 1.
Description
Only bits for which PCR1 is cleared are valid. The pull-
up MOS of P17 to P14 and P12 to P10 pins enter the
on-state when these bits are set to 1, while they enter
the off-state when these bits are cleared to 0.
Bit 3 is a reserved bit. This bit is always read as 1.
