Information

• NVICIABR2
• NVICIPR21
• To determine the particular IRQ's bitfield location within these particular registers:
• NVICISER2, NVICICER2, NVICISPR2, NVICICPR2, NVICIABR2 bit
location = IRQ mod 32 = 21
• NVICIPR21 bitfield starting location = 8 * (IRQ mod 4) + 4 = 12
Since the NVICIPR bitfields are 4-bit wide (16 priority levels), the NVICIPR21
bitfield range is 12-15
Therefore, the following bitfield locations are used to configure the LPTMR interrupts:
• NVICISER2[21]
• NVICICER2[21]
• NVICISPR2[21]
• NVICICPR2[21]
• NVICIABR2[21]
• NVICIPR21[15:12]
