Preliminary W78C33B

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 W78C33B 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.
2. PORT4
Another bit-addressable port P4 is also available and only 4 bits (P4<3:0>) can be used. This port
address is located at 0D8H with the same function as that of port P1.
Example: P4
REG
0D8H
; Output data "A" through P4.0
P4.3.
MOV
A, P4
; Read P4 status to Accumulator.
SETB
P4.0
; Set bit P4.0
CLR
P4.1
; Clear bit P4.1
MOV
P4, #0AH
