Each Capture register is associated with a device pin and may be loaded with the Timer
Counter value when a specified event occurs on that pin. The settings in the Capture
Control Register register determine whether the capture function is enabled, and whether
a capture event happens on the rising edge of the associated pin, the falling edge, or on
both edges.

The External Match Register provides both control and status of the external match pins
CAP32Bn_MAT[3:0].
Match events for Match 0 and Match 1 in each timer can cause a DMA request.
If the match outputs are configured as PWM output, the function of the external match
registers is determined by the PWM rules

Capture on CT32Bn_CAP3 rising edge: a sequence of 0 then 1 on CT32Bn_CAP3 will
cause CR3 to be loaded with the contents of TC.
Enabled.
Disabled.
Capture on CT32Bn_CAP3 falling edge: a sequence of 1 then 0 on CT32Bn_CAP3 will
cause CR3 to be loaded with the contents of TC.
Enabled.
Disabled.
Interrupt on CT32Bn_CAP3 event: a CR3 load due to a CT32Bn_CAP3 event will
generate an interrupt.
Enabled.
Disabled.
Reserved, user software should not write ones to reserved bits. The value read from a
reserved bit is not defined.
