Quadrature Encoder Interface Peripheral Ready (PRQEI)
The PRQEI register indicates whether the QEI modules are ready to be accessed by software following a change in status of power, run mode clocking, or reset. A power change is initiated if the corresponding PCQEI bit is changed from 0 to 1. A run mode clocking change is initiated if the corresponding RCGCQEI bit is changed. A reset change is initiated if the corresponding SRQEI bit is changed from 0 to 1.
The PRQEI bit is cleared on any of the preceding events and is not set again until the module is completely powered, enabled, and internally reset.
PRQEI is shown in Figure 4-190 and described in Table 4-218.
