PRELIMINARY DATA SHEET
19. Capture Compare Module (CAPCOM)
The IC contains two Capture Compare Modules (CAPCOM).
A CAPCOM is a complex relative timer. It comprises a free
running 16bit Capture Compare Counter (CCC) and a num-
ber of Subunits (SU). The timer value can be read by SW.
A SU is able to capture the relative time of an external event
input and to generate an output signal when the CCC passes
a predefined timer value. Three types of interrupts enable
interaction with SW. Special functionality provides an inter-
face to the asynchronous external world.
