Interrupt
The pins used for interfacing the compliant external devices may be multiplexed with PIO lines.
The programmer must first program the PIO controllers to assign the EMAC pins to their periph-
eral functions. In RMII mode, unused pins (see
used as general I/O lines.
The EMAC may be clocked through the Power Management Controller (PMC), so the program-
mer must first configure the PMC to enable the EMAC clock.
If not used, about 400 µA current consumption can be saved by switching the EMAC in Local
Loopback Mode with the following sequence:
The EMAC has an interrupt line connected to the Advanced Interrupt Controller (AIC). Handling
the EMAC interrupt requires programming the AIC before configuring the EMAC.
• EMAC clock is enabled
• EMAC Local Loopback is enabled
• EMAC clock is disabled
