Reset
The external RESET signal is sampled at S5P2. To take effect, it must be held high for at least two
machine cycles while the oscillator is running.
An internal trigger circuit in the reset line is used to deglitch the reset line when the W78C32C is used
with an external RC network. The reset logic also has a special glitch removal circuit that ignores
glitches on the reset line.
During reset, the ports are initialized to FFH, the stack pointer to 07H, PCON (with the exception of
bit 4) to 00H, and all of the other SFR registers except SBUF to 00H. SBUF is not reset.
