Notes: 1. Pins marked NC should be left unconnected.
2. For details on witer mode, refer to 18.2, Writer Mode, 19.6 Flash Memory Writer Mode
(H8/3334YF), 20.6 Flash Memory Writer Mode (H8/3337YF) and 21.5, Flash Memory
Writer Mode (H8/3337SF).
3. In this chip, except for the S-mask model (single-power-supply specification), the same
pin is used for STBY and FVPP. When this pin is driven low, a transition is made to
hardware standby mode. This happens not only in the normal operating modes (modes
1, 2, and 3), but also when programming the 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 VCC level
except when programming (FVPP = 12 V).
* Differs as in mode 3, depending on whether the host interface is enabled or disabled.
