W78LE365/W78L365A

5.5

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 W78L365A 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.
