10.3.10.4 IRQs and Flags

Internal device flags such as overcurrent, under-voltage, etc can be routed as interrupts. The device has 4 interrupts that can be routed to any of the 10 GPIO pins. If more than one flag is assigned to the same interrupt the interrupt output is the logical OR-ing of all flags. If multiple flags are assigned to the same interrupt the host should then query the flags sticky register to determine which event triggered the interrupt. The 10 GPIO pins can be configured for any interrupt and can be configured using B0_P1_R61 thru B0_P1_R70.

Table 3. Interrupt Registers

Flag Name	Flag Description	Sticky Register Bit	Register to Route Flag to Interrupt
Flag 1	Over Current	B0_P0_R104[7]	B0_P1_R108[6:4]
Flag 2	Under Voltage	B0_P0_R104[6]	B0_P1_R108[2:0]
Flag 3	Clock Error Detection 1	B0_P0_R104[5]	B0_P1_R109[6:4]
Flag 4	Over Temperature	B0_P0_R104[4]	B0_P1_R109[2:0]
Flag 5	Brownout	B0_P0_R104[3]	B0_P1_R110[6:4]
Flag 6	Clock Error Detection 2	B0_P0_R104[2]	B0_P1_R110[2:0]
Flag 7	SAR Complete	B0_P0_R104[1]	B0_P1_R111[6:4]

For example, to route the Brownout and Under Voltage flags to GPIO5 (Pin IRQ_GPIO5) the following register settings would be used. The flag Brownout would be routed to Interrupt 1 by setting B0_P1_R110[6:4]=001 and flag Under Voltage would be also routed to interrupt 1 by setting B0_P1_R108[2:0]=001. The pin IRQ_GPIO5 would be set to use interrupt 1 by setting B0_P1_R64[4:0]=0x07
