Note:
MC68HC05X16
Oscillator division ratio selection (divide-by-2, -4, -8 or -10)
Oscillator start-up delay following power-on or STOP (t
Automatic watchdog enable/disable following a power-on or external reset
Watchdog enable/disable during WAIT mode
Wired-OR interrupt enable
Resistive pull-downs on ports B and/or C
It is recommended that an external clock is always used if t
will prevent any problems arising from oscillator stability when the device is put into
STOP mode.
