Timer/Counter 2 with Compare/Capture/Reload
The timer 2 of the C505 provides additional compare/capture/reload features. which allow the
selection of the following operating modes:
The block diagram in figure 11 shows the general configuration of timer 2 with the additional
compare/capture/reload registers. The I/O pins which can used for timer 2 control are located as
multifunctional port functions at port 1.
