6.5.1 Interrupt Set Enable Register 0 register
The ISER0 register allows to enable peripheral interrupts or to read the enabled state of
those interrupts. Disable interrupts through the ICER0 (Section 6.5.2
).
The bit description is as follows for all bits in this register:
Write — Writing 0 has no effect, writing 1 enables the interrupt.
Read — 0 indicates that the interrupt is disabled, 1 indicates that the interrupt is enabled.
IPR5 R/W 0x414 Interrupt Priority Registers 5. This register allows assigning a priority
to each interrupt. This register contains the 2-bit priority fields for
interrupts 12 to 15.
0 Table 71
IPR6 R/W 0x418 Interrupt Priority Registers 6. This register allows assigning a priority
to each interrupt. This register contains the 2-bit priority fields for
interrupts 24 to 27.
0 Table 72
IPR7 R/W 0x41C Interrupt Priority Registers 7. This register allows assigning a priority
to each interrupt. This register contains the 2-bit priority fields for
interrupts 28 to 31.
