Register 83: Quadrature Encoder Interface Software Reset (SRQEI), offset
0x544
The SRQEI register provides software the capability to reset the available QEI modules.
A peripheral is reset by software using a simple two-step process:
1. Software sets a bit (or bits) in the SRQEI register. While the SRQEI bit is 1, the peripheral is
held in reset.
2. Software completes the reset process by clearing the SRQEI bit.
There may be latency from the clearing of the SRQEI bit to when the peripheral is ready for use.
Software should check the corresponding PRQEI bit to verify that the QEI Module registers are
ready to be accessed.
Important: This register should be used to reset the QEI modules.

Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
