Not available in the H8S/2426 Group.
Emulator enable pin. In normal operating mode, this pin should be fixed low.
Driving this pin high in the flash-memory version enables the on-chip emulation function.
When the on-chip emulation function is in use, pins P53, PG4, PG5, PG6, and WDTOVF are used exclusively as the on-chip emulator pins.
The VCL pin should be connected to an external capacitor.
