PRESCALER REGISTER (PRSR)
R251 - Read/Write
Register Page: 10
Reset value: 0000 0000 (00h)
This register holds the preset value for the 8-bit
prescaler. The PRSR content may be modified at
any time, but it will be loaded into the prescaler at
the following prescaler underflow, or as a conse-
quence of a counter reload (either by software or
upon external request).
Following a RESET condition, the prescaler is au-
tomatically loaded with 00h, so that the prescaler
divides by 1 and the maximum counter clock is
generated (Crystal oscillator clock frequency divid-
ed by 6 when MODER.5 = DIV2 bit is set).
The binary value programmed in the PRSR regis-
ter is equal to the divider value minus one. For ex-
ample, loading PRSR with 24 causes the prescal-
er to divide by 25.
