Hi guys,
For those of you who want to adapt your Jallib samples or your own
programs to the new device files: with many PICs the 'pragma fuse_def
WDT' has changed DISABLED to CONTROL. This means 2 things:
1. In the old device files DISABLED may not have had the effect
that is was supposed to have, because it effectively was CONTROL.
2. In addition to changing it to CONTROL you should add a line:
WDTCON_SWDTEN = 0b_0
because CONTROL means that WDT is software controlled.
Note 1: It may also be the other way around (CONTROL -> DISABLED)
Note 2: The decriptions behind the fuse_def WDT may be misleading. These
come right from MPLAB-X, and for example the 16f631 has:
DISABLED = 0x0 -- WDT disabled and can be enabled by SWDTEN bit of the
WDTCON register
But this PIC has no WDTCON register and therefore has no capability to
control WDT by software! Blame Microchip!
Regards, Rob.
