1.
Ports P0, 1, 3 are set to "1" and ports P2, 4,
5, 6, 7, 8 are reset to "0" directly by the reset
input signal.
Ports P0, 1, 3 are set to "1" and ports P2, 4,
5, 6, 7, 8 are initialized during reset cycle.
After being reset, the timer continues to stop
until data is set in it.
It is undefined whether the timer starts or
not after being reset. Therefore, the timer
should be initialized by software.
Serial out F/F (SOF/F) is set to "0" after being
reset.
It is undefined whether serial out F/F
(SOF/F) is "0" or "1" after being reset.
Therefore the serial out F/F should be
initialized by software.
