EXTENDED FUNCTION TIMER (Cont’d)
10.3.5 Register Description
Each Timer is associated with three control and
one status registers, and with six pairs of data reg-
isters (16-bit values) relating to the two input cap-
tures, the two output compares, the counter and
the alternate counter.
Notes:
1. In the register description on the following pag-
es, register and page numbers are given using the
example of Timer 0. On devices with more than
one timer, refer to the device register map for the
adresses and page numbers.
2. To work correctly with register pairs, it is strong-
ly recommended to use single byte instructions.
Do not use word instructions to access any of the
16-bit registers.
