Table 4.4. ISER bit assignments
Bits
Name
Function
[31:0]
SETENA
Interrupt set-enable bits.
Write:
0 = no effect1 = enable
interrupt.Read:
0 = interrupt disabled
1 = interrupt enabled.
If a pending interrupt is enabled, the NVIC activates the interrupt based on its priority. If an interrupt is
not enabled, asserting its interrupt signal changes the interrupt state to pending, but the NVIC never
activates the interrupt, regardless of its priority.
4.2.3 Interrupt Clear-enable Registers
The ICER0 and ICER1 registers disable interrupts, and show which interrupts are enabled. See:
the register summary in Table 4.2 (p. 88) for the register attributes
Table 4.3 (p. 89) for which interrupts are controlled by each register.
The bit assignments are:

Read:
0 = interrupt disabled
1 = interrupt enabled.
4.2.4 Interrupt Set-pending Registers
The ISPR0 and ISPR1 registers force interrupts into the pending state, and show which interrupts are
pending. See:
the register summary in Table 4.2 (p. 88) for the register attributes
Table 4.3 (p. 89) for which interrupts are controlled by each register.
The bit assignments are:
