14.4.3
This section describes interrupts originated by the ECT block. The MCU must service the interrupt
requests.
The ECT only originates interrupt requests. The following is a description of how the module makes a
request and how the MCU should acknowledge that request. The interrupt vector offset and interrupt
number are chip dependent.
14.4.3.1
This active high output will be asserted by the module to request a timer channel 7–0 interrupt to be
serviced by the system controller.
14.4.3.2
This active high output will be asserted by the module to request a modulus counter underflow interrupt to
be serviced by the system controller.
14.4.3.3
This active high output will be asserted by the module to request a timer pulse accumulator B overflow
interrupt to be serviced by the system controller.
14.4.3.4
This active high output will be asserted by the module to request a timer pulse accumulator A input
interrupt to be serviced by the system controller.
