These bits enable or disable wait-state control
WCER is initialized to H'FF by a reset and in hardware standby mode. It is not initialized in
software standby mode.
Bits 7 to 0—Wait-State Controller Enable 7 to 0 (WCE7 to WCE0): These bits enable or
disable wait-state control of external three-state-access areas.

(Initial value)
Since WCER enables or disables wait-state control of external three-state-access areas, these
settings are meaningless in single-chip mode (mode 7).
