Normal Interrupt Summary
Normal Interrupt Summary bit value is the logical OR of the following
when the corresponding interrupt bits are enabled in EMACDMAIM
register:
■ EMACDMARIS register, bit [0]: Transmit Interrupt
■ EMACDMARIS register, bit[2]: Transmit Buffer Unavailable
■ EMACDMARIS register, bit[6]: Receive Interrupt
■ EMACDMARIS register, bit[14]: Early Receive Interrupt
Only unmasked bits (interrupts for which interrupt enable is set in the
EMACDMAIM register) affect the Normal Interrupt Summary bit.
This is a sticky bit and must be cleared (by writing 1 to this bit) each
time a corresponding bit, which causes NIS to be set, is cleared.
