DK-TM4C129X
Register 20: Interrupt 0-31 Active Bit (ACTIVE0), offset 0x300
Register 21: Interrupt 32-63 Active Bit (ACTIVE1), offset 0x304
Register 22: Interrupt 64-95 Active Bit (ACTIVE2), offset 0x308
Register 23: Interrupt 96-127 Active Bit (ACTIVE3), offset 0x30C
Note:
This register can only be accessed from privileged mode.
The UNPENDn registers indicate which interrupts are active. Bit 0 of ACTIVE0 corresponds to
Interrupt 0; bit 31 corresponds to Interrupt 31. Bit 0 of ACTIVE1 corresponds to Interrupt 32; bit 31
corresponds to Interrupt 63. Bit 0 of ACTIVE2 corresponds to Interrupt 64; bit 31 corresponds to
Interrupt 95. Bit 0 of ACTIVE3 corresponds to Interrupt 96; bit 17 corresponds to Interrupt 113.
Interrupt 0; bit 31 corresponds to Interrupt 31. Bit 0 of ACTIVE1 corresponds to Interrupt 32; bit 31
corresponds to Interrupt 63. Bit 0 of ACTIVE2 corresponds to Interrupt 64; bit 31 corresponds to
Interrupt 95. Bit 0 of ACTIVE3 corresponds to Interrupt 96; bit 17 corresponds to Interrupt 113.
See Table 2-9 on page 125 for interrupt assignments.
Caution – Do not manually set or clear the bits in this register.
