ST92141 - INTERRUPTS
INTERRUPT REGISTERS (Cont’d)
EXTERNAL INTERRUPT PENDING REGISTER
(EIPR)
R243 - Read/Write
Register Page: 0
Reset value: 0000 0000 (00h)
Bit 7 = IPD1:
INTD1 Interrupt Pending bit
Bit 6 = IPD0:
INTD0 Interrupt Pending bit
Bit 5 = IPC1:
INTC1 Interrupt Pending bit
Bit 4 = IPC0:
INTC0 Interrupt Pending bit
Bit 3 = IPB1:
INTB1 Interrupt Pending bit
Bit 2 = IPB0:
INTB0 Interrupt Pending bit
Bit 1 = IPA1:
INTA1 Interrupt Pending bit
Bit 0 = IPA0:
INTA0 Interrupt Pending bit
These bits are set by hardware on occurrence of a
trigger event (as specified in the EITR register)
and are cleared by hardware on interrupt acknowl-
edge. They can also be set by software to imple-
ment a software interrupt.
0: No interrupt pending
1: Interrupt pending
EXTERNAL INTERRUPT MASK-BIT REGISTER
(EIMR)
R244 - Read/Write
Register Page: 0
Reset value: 0000 0000 (00h)
Bit 7 = IMD1:
INTD1 Interrupt Mask
Bit 6 = IMD0:
INTD0 Interrupt Mask
Bit 5 = IMC1:
INTC1 Interrupt Mask
Bit 4 = IMC0:
INTC0 Interrupt Mask
Bit 3 = IMB1:
INTB1 Interrupt Mask
Bit 2 = IMB0:
INTB0 Interrupt Mask
Bit 1 = IMA1:
INTA1 Interrupt Mask
Bit 0 = IMA0:
INTA0 Interrupt Mask
These bits are set and cleared by software.
0: Interrupt masked
1: Interrupt not masked (an interrupt is generated if
the IPxx and IEN bits = 1)

PRIORITY
LEVEL
REGISTER (EIPLR)
R245 - Read/Write
Register Page: 0
Reset value: 1111 1111 (FFh)
Bit 7:6 = PL2D, PL1D:
INTD0, D1 Priority Level.
Bit 5:4 = PL2C, PL1C:
INTC0, C1 Priority Level.
Bit 3:2 = PL2B, PL1B:
INTB0, B1 Priority Level.
Bit 1:0 = PL2A, PL1A:
INTA0, A1 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 Channels A0, B0, C0 and D0 and
at 1 for Channels A1, B1, C1 and D1.
