I/O Multiplexing and Control Module (IOMM)
6.5.11 Control for Input Connections to eQEPx Modules
Each eQEPx module has four inputs from the device terminals. These inputs can be connected to the
eQEPx 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 eQEPx
module.
