INTERRUPT REGISTERS (Cont’d)
INTERRUPT PRIORITY LEVEL REGISTER LOW
(SIPLRL)
R253 - Read/Write
Register Page: Page 60
Reset Value : 1111 1111
Bits 7:6 = PL2H, PL1H: INTH0,H1 Priority Level.
Bits 5:4 = PL2G, PL1G: INTG0, G1 Priority Level.
Bits 3:2 = PL2F, PL1F: INTF0, F1 Priority Level.
Bits 1:0 = PL2E, PL1E: INTE0, E1 Priority Level.
These bits are set and cleared by software.
The priority is a three-bit value. The LSB is fixed by
hardware at 0 for even channels and at 1 for odd
channels

INTERRUPT FLAG REGISTER HIGH
(SFLAGRH)
R254 - Read Only
Register Page: 60
Reset Value : 0000 0000
Bit 0 = OUFI0 : Overrun flag for INTI0
This bit is set and cleared by hardware. It indicates
if more than one interrupt event occured on INTI0
before the IPI0 bit in the SIPRH register has been
cleared.
0 : No overrun
1 : Overrun has occurred on INTI0
INTERRUPT FLAG REGISTER LOW
(SFLAGRL)
R255 - Read Only
Register Page: 60
Reset Value : 0000 0000
Bits 7:0 = OUFxx : Overrun flag for channel xx
These bits are set and cleared by hardware. They
indicate if more than one interrupt event occurs on
the associated channel before the pending bit in
the SIPRL register has been cleared.
0 : No overrun
1 : Overrun has occurred on channel xx
