I/O

INTS/

OD6,O3/6

General-Purpose I/O Port 0, bits 0-7. Each pin is configured independent-

ly as input or I/O, with or without static pull-up, and with either open-drain or

push-pull output type. The port supports interrupt assertion, and each pin

can be enabled or masked as an interrupt source.
