Technical Data
NOTE:
Address:
When bit DDRFx is a logic 1, reading address $0009 reads the PTFx
data latch. When bit DDRFx is a logic 0, reading address $0009 reads
the voltage level on the pin. The data latch can always be written,
regardless of the state of its data direction bit.
the operation of the port F pins.
Port G is a 3-bit, general-purpose, bidirectional I/O port.
The pins of port G are available only in the 64-pin QFP.
The port G data register (PTG) contains a data latch for each of the three
port G pins.
X = Don’t care
Hi-Z = High impedance
