6.3.2 High-Current Output Registers
Writes to the high-current output registers cause the high-current output pins to change
state to match the bits in the register. These bits default to ‘1’ on Reset, corresponding to
a HIGH output level.

BIT NAME DESCRIPTION
7:0 D
Data When this field is read, the value of the last write is returned. When this field
is written, the output pins are updated to match the state of the register bits, with a
logic HIGH corresponding to a ‘1’ bit. Port 2 is bit addressible. Individual bits can
be altered without affecting the others.
