gmacgrp_interrupt_mask 

          Register 15 (Interrupt Mask Register)  

The Interrupt Mask Register bits enable you to mask the interrupt signal because of the corresponding event in the Interrupt Status Register. The interrupt signal is sbd_intr_o in the GMAC-AHB, GMAC-AXI, and GMAC-DMA configuration and mci_intr_o in the GMAC-MTL and GMAC-CORE configuration.

Access: RW

Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

10 lpiim 
LPI Interrupt Mask

When set, this bit disables the assertion of the interrupt signal because of the setting of the LPI Interrupt Status bit in Register 14 (Interrupt Status Register).
This bit is valid only when you select the Energy Efficient Ethernet feature during core configuration. In all other modes, this bit is reserved.
Value Description

9 tsim 
Timestamp Interrupt Mask

When set, this bit disables the assertion of the interrupt signal because of the setting of Timestamp Interrupt Status bit in Register 14 (Interrupt Status Register).
This bit is valid only when IEEE1588 timestamping is enabled. In all other modes, this bit is reserved.
