Notes:
Port 0 (P07–P00)
Port 0 is an 8-bit, bidirectional, CMOS-compatible port. These eight I/O lines are
configured under software control as a nibble I/O port. The output drivers are push-pull or
open-drain controlled by bit D2 in the PCON register.
If one or both nibbles are needed for I/O operation, they must be configured by writing to
the Port 0 mode register. After a hardware reset, Port 0 is configured as an input port.
An optional pull-up transistor is available as a mask option on all Port 0 bits with nibble
select.
put with outputting logic ONE, it is a floating port and will read back as ZERO.
The following instruction will set P00-P07 all LOW.
AND P0,#%F0
1. Internal pull-ups are disabled on any given pin or group of port
2. The Port 0 direction is reset to its default state following an SMR.
