Reset conditions
The HT9580 will reset the whole chip when the
following conditions are met:
Power On
The external RESET pin is held low for at
least 1 ms
The WDT overflows
The input is used to reset the C. Reset must be
held low at least 1 ms after VDD reaches oper-
ating voltage from a power down. A positive
transition on the chip reset will then cause an
initialization sequence to begin. After the sys-
tem is operating, a low on this line of at least 1
ms in duration will cause
positive edge is detected, there is an initializa-
tion sequence lasting 8-clock cycles. Then the
interrupt mask flag is set, the decimal mode is
cleared and the program counter is loaded with
the restart vector from locations FFFC (low
byte) and FFFD (high byte). This is the start lo-
cationforprogramcontrol.Thisinputshouldbe
