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 two ways:
1. Double-synchronized using VCLK3, or
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.
