Description
Primary Inputs [15:0] Mask. Bits [15:0] correspond to Primary Inputs [15:0], bit 2 is
reserved (i.e., no IRQ2).
0: Mask the interrupt source.
1: Do not mask the interrupt source.
For Primary Inputs [15:0] sources, see Table 4-12 on page 104.
Description
Reserved. Set to 0.
LPC Inputs [15:0] Enable. Bits [15:0] correspond to LPC Inputs [15:0], bit 2 is don’t
care (i.e., no IRQ2).
0: Disable interrupt source.
1: Enable interrupt source.
For LPC Inputs [15:0] sources, see Table 4-12 on page 104.
