Clock Out
A calibration instruction is programmed into the last address of the implemented program
memory. This instruction contains the calibration value for the internal RC oscillator. This value
is programmed as a RETLW XX instruction where XX is the calibration value. In order to retrieve
the calibration value, issue a CALL YY instruction where YY is the last location in the device’s user
accessible program memory. The calibration value is now loaded in the W register. The program
should then perform a MOVWF OSCCAL instruction to load the value into the internal RC oscillator
calibration register.
of the program memory.
Table 2-5:
The internal RC oscillator can be configured to provide a clock out signal on the CLKOUT pin
when the configuration word address (2007h) is programmed with FOSC2, FOSC1, FOSC0
equal to ‘101’ for Internal RC or ‘111’ for External RC. CLKOUT, which is divided by 4, can be
used for test purposes or to synchronize other logic.
When the calibration value of the internal RC oscillator is accidently erased, the clock out feature
allows the user to determine what the calibration value should be. This is achieved by writing a
program which modifies (increments/decrements) the value of the OSCCAL register. When the
CLKOUT pin is at 4 MHz ( 1.5%) at 5V and 25˚C, the OSCCAL register has the correct calibra-
tion value. This value then needs to be written to a port or shifted out serially, so that the value
can be written down and programmed into the calibration location.

calibration value for the internal oscillator.
Prior to erasing a windowed device, the internal oscillator calibration value must be
saved. It is a good idea to write this value on the package of the device to ensure
that the calibration value is not accidently lost.
This saved valued must be restored into program memory calibration location before
programming the device.
