Note: In this chip, except for the S-mask model (single-power-supply specification), the same pin
is used for STBY and FV
standby mode. This occurs not only in the normal operating modes (modes 1, 2, and 3), but
also when programming flash memory with a PROM writer. When using a PROM
programmer to program dual-power-supply flash memory, therefore, the PROM
programmer specifications should provide for this pin to be held at the V
when programming (FV
