Mask options for the MC68HC05X16
The MC68HC05X16 has six mask options that are programmed during manufacture and must be
speciï¬ed on the order form.
⢠Oscillator division ratio selection (divide-by-2, -4, -8 or -10)
⢠Oscillator start-up delay following power-on or STOP (tPORL) = 16 or 4064 cycles
⢠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
Note:
It is recommended that an external clock is always used if tPORL is set to 16 cycles. This
will prevent any problems arising from oscillator stability when the device is put into
STOP mode.
