24.4 General description
<Document ID>
User manual
The State Configurable Timer (SCT) allows a wide variety of timing, counting, output
modulation, and input capture operations.
The most basic user-programmable option is whether a SCT operates as two 16-bit
counters or a unified 32-bit counter. In the two-counter case, in addition to the counter
value the following operational elements are independent for each half:
In the two-counter case, the following operational elements are global to the SCT, but
events, outputs, interrupts, and DMA requests can use match conditions from either
counter:
Remark: This document uses the term “bus error” to indicate a SCT response that makes
the processor take an exception.
