The Capture Control Register is used to control whether one of the four Capture Registers
is loaded with the value in the Timer Counter when the capture event occurs, and whether
an interrupt is generated by the capture event. Setting both the rising and falling bits at the
same time is a valid configuration, resulting in a capture event for both edges. In the
description below, “n” represents the Timer number, 0 or 1.
Capture on CT32Bn_CAP0 rising edge: a sequence of 0 then 1 on CT32Bn_CAP0 will
cause CR0 to be loaded with the contents of TC.
Enabled.
Disabled.
Capture on CT32Bn_CAP0 falling edge: a sequence of 1 then 0 on CT32Bn_CAP0 will
cause CR0 to be loaded with the contents of TC.
Enabled.
Disabled.
Interrupt on CT32Bn_CAP0 event: a CR0 load due to a CT32Bn_CAP0 event will
generate an interrupt.
Enabled.
Disabled.
Capture on CT32Bn_CAP1 rising edge: a sequence of 0 then 1 on CT32Bn_CAP1 will
cause CR1 to be loaded with the contents of TC.
Enabled.
Disabled.
Capture on CT32Bn_CAP1 falling edge: a sequence of 1 then 0 on CT32Bn_CAP1 will
cause CR1 to be loaded with the contents of TC.
Interrupt on CT32Bn_CAP1 event: a CR1 load due to a CT32Bn_CAP1 event will
generate an interrupt.
Capture on CT32Bn_CAP2 rising edge: a sequence of 0 then 1 on CT32Bn_CAP2 will
Capture on CT32Bn_CAP2 falling edge: a sequence of 1 then 0 on CT32Bn_CAP2 will
