Global Interrupt Enable Status Register (Read/Write) - (BAR0 + 0x0000 0000)
This read/write register is used to: enable board interrupt, determine the
pending status of interrupts.
The function of each of the interrupt register bits are described in Table 3.3.
This register can be read or written with either 8-bit, 16-bit, or 32-bit data
transfers. A power-up or system reset sets all interrupt register bits to 0.
Table 3.3 Global Interrupt
Register
Note that any registers/bits not
mentioned will remain at the
default value logic low.
Bit(s)
FUNCTION
0
Board Interrupt Enable Bit. This bit must be set to logic “1” to
enable generation of interrupts from the AP module. Setting
this bit to logic “0” will disable board interrupts. (Read/Write
Bit)

1
Enabled
1
Interrupt Pending Status Bit. This bit can be read to
determine the interrupt pending status of the AP module.
When this bit is logic “1” an interrupt is pending and will cause
an interrupt request if bit-0 of the register is set. When this
b
it is logic “0” an interrupt is not being requested
.
