Note:
Port 0 (P00–P07)
Port 0 is an 8-bit, bidirectional, CMOS-compatible port. These eight I/O lines are config-
ured 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 01 mode register (P01M). After a hardware reset or Stop Mode Recovery, Port 0
is configured as an input port.
An optional pull-up transistor is available as a OTP option bit on all Port 0 bits with nibble
select.
The Port 0 direction is reset to be input following an SMR.
open-drain output with output logic as ONE, it is a floating port and reads back as
ZERO. The following instruction sets P00-P07 all Low.
