:wink:
Why do you want to do this?.
Errrrm Nigel, someone once told me that the point of 32khz was all about saving power :wink: :wink: :roll: :lol:
Peter, take a look at the Datasheet, it tells you how to do what you want......
"14.3 Special Feature: Dual Speed
Oscillator Modes
A software programmable dual speed oscillator mode
is provided when the PIC16F62X is configured in either
ER or INTRC oscillator modes. This feature allows
users to dynamically toggle the oscillator speed
between 4MHz and 37kHz. In ER mode, the 4MHz setting
will vary depending on the size of the external
resistor. Also in ER mode, the 37kHz operation is fixed
and does not vary with resistor size. Applications that
require low current power savings, but cannot tolerate
putting the part into sleep, may use this mode."
Be aware though that the 32khz internal osc may not be as accurate as the external crystal you originally wanted to use, check the specs in the datasheet....
Hope this helps!
