6.2.4
WCER is an 8-bit readable/writable register that enables or disables wait-state control of external
three-state-access areas by the wait-state controller.
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.
Since WCER enables or disables wait-state control of external three-state-access areas, these
settings are meaningless in single-chip mode (mode 7).
