Syntax: RESET
Operation: (PC) <-- vector(0)
(PSW) <-- vector(0)
(SFRs) <-- reset values (refer to the description of reset for details)
Description: The chip is reset exactly as if the external hardware reset has been asserted with the
exception that it does not sample inputs for configuration, e.g.,
EA, BUSW, etc. When a RESET
instruction is executed, the chip is internally reset, but no external
RESET pulse is generated.
The above inputs which are latched during rising edge of a
RESET pulse, hence does not affect
the chip configuration.
Flags Updated: The entire PSW is set to the value specified in the reset vector.
