22.2.1
Register 22-14 shows the WDTCON register. This is a
readable and writable register which contains a control
bit that allows software to override the WDT enable
Configuration bit, but only if the Configuration bit has
disabled the WDT.
REGISTER 22-14: WDTCON: WATCHDOG TIMER CONTROL REGISTER
TABLE 22-2:
22.3
The overall structure of the code protection on the
PIC18 Flash devices differs significantly from other
PIC
The user program memory is divided into five blocks.
One of these is a boot block of 0.5K or 2K bytes,
depending on the device. The remainder of the mem-
ory is divided into individual blocks on binary boundar-
ies.
Each of the five blocks has three code protection bits
associated with them. They are:
• Code-Protect bit (CPn)
• Write-Protect bit (WRTn)
• External Block Table Read bit (EBTRn)
