Interrupt Mask Set/Read Register - IMS (0x000D0; RW)
Reading this register returns which bits have an interrupt mask set. An interrupt is
enabled if its corresponding mask bit is set to 1b, and disabled if its corresponding
mask bit is set to 0b. A PCIe interrupt is generated whenever one of the bits in this
register is set, and the corresponding interrupt condition occurs. The occurrence of an
interrupt condition is reflected by having a bit set in the Interrupt Cause Read register
(see
A particular interrupt can be enabled by writing a 1b to the corresponding mask bit in
this register. Any bits written with a 0b, are unchanged. Thus, if software desires to
disable a particular interrupt condition that had been previously enabled, it must write
to the Interrupt Mask Clear register (see
a bit in this register.
When the CTRL_EXT.INT_TIMERS_CLEAR_ENA bit is set, then following writing all 1b's
to the IMS register (enable all interrupts) all interrupt timers are cleared to their initial
value. This auto clear provides the required latency before the next INT event.
