No.
Mask 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 activated, otherwise the XST is disabled.
2
WDT source selection. There are three types of selection: on-chip RC oscillator, in-
struction clock or disable the WDT.
3
CLRWDT times selection. This option defines the way to clear the WDT by instruc-
tion. 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

5
Pull-high selection. This option is to decide whether the pull-high resistance is visi-
ble or not in the input mode of the I/O ports. Each bit of an I/O port can be independ-
ently selected.
6
Special power on reset. This option defines the function will reset the chip to prevent
incorrect status.
If the special power on reset is enabled, the chip must not enter the HALT mode.
