I/O Multiplexing and Control Module (IOMM)
Of the three internal error events for the trip-zone inputs, nTZ4 is connected to the eQEPx error output
signal. There are two eQEP modules on this microcontroller, and registers in the I/O multiplexing module
are used to allow a flexible scheme for the connection between the eQEPx error signal and the nTZ4
inputs of the ePWMx modules.

6.5.10 Control for Input Connections to eCAPx Modules
Each eCAPx module has a single input from the device terminals. This input can be connected to the
eCAPx module in one of two ways:
1. Double-synchronized using VCLK3
2. Double-synchronized using VCLK3 and then filtered through a 6-VCLK3-cycle counter
Registers in the I/O multiplexing module are used to control these input connections for each eCAPx
module.
