37.8.13 GMAC Interrupt Mask Register
This register is a read-only register indicating which interrupts are masked. All bits are set at Reset and can be reset individually by writing to the Interrupt Enable Register (GMAC_IER), or set individually by writing to the Interrupt Disable Register (GMAC_IDR).
For test purposes there is a write-only function to this register that allows the bits in the Interrupt Status Register to be set or cleared, regardless of the state of the mask register. A write to this register directly affects the state of the corresponding bit in the Interrupt Status Register, causing an interrupt to be generated if a 1 is written.
The following values are valid for all listed bit names of this register when read:
0: The corresponding interrupt is enabled.
1: The corresponding interrupt is not enabled.
