No.
ROM Code Option
1
OSC type selection. This option is to decide if an RC or Crystal oscillator is chosen as system
clock. If the Crystal oscillator is selected, the XST (Crystal Start-up Timer) default is acti-
vated, otherwise the XST is disabled.
2
WDT source selection. There are three types of selection: on-chip RC oscillator, instruction
clock or disable the WDT.
3
CLRWDTtimesselection.ThisoptiondefinesthewaytocleartheWDTbyinstruction. One
time means that the CLR WDT instruction can clear the WDT. Two times means only if
both of the CLR WDT1 and CLR WDT2 instructions have been executed, only then will the
WDT be cleared.
4
Wake-up selection. This option defines the wake-up function activity. External I/O pins (PA
and PC [0:3] only) all have the capability to wake-up the chip from a HALT.
5
Pull-high selection. This option is to decide whether the pull-high resistance is visible or not
in the input mode of the I/O ports. Each bit of an I/O port can be independently selected.
6
Special power on reset. This option defines the function will reset the chip to prevent incor-
rect status.
If the special power on reset is enabled, the chip must not enter the HALT mode.
