Port B general purpose input/output data—Data Register
Port B pins 7 through 0 are associated with address outputs ADDR[7:0] respectively in expanded modes. In
emulation modes the address is multiplexed with IVD[7:0]. In normal expanded mode pin 0 is related to the UDS
input.
When not used with the alternative function, these pins can be used as general purpose I/O.
If the associated data direction bits of these pins are set to 1, a read returns the value of the port register, otherwise
the buffered pin input state is read.
Port A Data Direction—
This register controls the data direction of pins 7 through 0.
The external bus function forces the I/O state to be outputs for all associated pins. In this case the data direction bits
will not change.
When operating a pin as a general purpose I/O, the associated data direction bit determines whether it is an input
or output.
1 Associated pin is configured as output.
0 Associated pin is configured as high-impedance input.
