Note:
Port A Data Direction Register (PADDR)
PADDR is an 8-bit write-only register that can select input or output for each pin in port A. When
pins are used for TPC output, the corresponding PADDR bits must also be set.
While port A acts as an I/O port, a pin in port A becomes an output pin if the corresponding
PADDR bit is set to 1, and an input pin if this bit is cleared to 0. In modes 3, 4, and 6, PA
fixed at 1 and PA
PADDR is a write-only register. Its value cannot be read. All bits return 1 when read.
PADDR is initialized to H'00 by a reset and in hardware standby mode in modes 1, 2, 5, and 7.
It is initialized to H'80 by a reset and in hardware standby mode in modes 3, 4, and 6. In software
standby mode it retains its previous setting. If a PADDR bit is set to 1, the corresponding pin
maintains its output state in software standby mode.
