Reset Vector
Interrupt Vector
Calibration Information
On any device, a reset forces the Program Counter (PC) to address 0h. We call this address the
“Reset Vector Address” since this is the address that program execution will branch to when a
device reset occurs.
Any reset will also clear the contents of the PCLATH register. This means that any branch at the
Reset Vector Address (0h) will jump to that location in PAGE0 of the program memory.
When an interrupt is acknowledged the PC is forced to address 0004h. We call this the “Interrupt
Vector Address”. When the PC is forced to the interrupt vector, the PCLATH register is not mod-
ified. Once in the service interrupt routine (ISR), this means that before any write to the PC, the
PCLATH register should be written with the value that will specify the desired location in program
memory. Before the PCLATH register is modified by the Interrupt Service Routine (ISR) the con-
tents of the PCLATH may need to be saved, so it can be restored before returning from the ISR.
Some devices have calibration information stored in their program memory. This information is
programmed by Microchip when the device is under final test. The use of these values allows the
application to achieve better results. The calibration information is typically at the end of program
memory, and is implemented as a RETLW instruction with the literal value being the specified cal-
ibration information.
Note:
For windowed devices, write down all calibration values BEFORE erasing. This
allows the device’s calibration values to be restored when the device is re-pro-
grammed. When possible writing the values on the package is recommended.
