Ethernet MAC Peripheral Ready (PREMAC)
The PREMAC register indicates whether the Ethernet module is 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 PCEMAC bit is changed from 0 to 1. A run mode clocking change is initiated if the corresponding RCGCEMAC bit is changed. A reset change is initiated if the corresponding SREMAC bit is changed from 0 to 1.
The PREMAC bit is cleared on any of the preceding events and is not set again until the module is completely powered, enabled, and internally reset.
PREMAC is shown in Figure 4-195 and described in Table 4-223.
