A4 Active low chip reset input.
The SYM53C040 has an
internal power-on reset circuit
which can be relied upon for
initializing the chip. If the
SYM53C040 watchdog timer
is used and it expires, it can
force an internal chip reset
and assert the RESET/ pin
LOW to reset external devices
(if bit 7 in register 0xFF05 is
set).
