10.20.4 Interrupt Set-pending Registers
The ISPR0-ISPR1 register forces interrupts into the pending state, and shows which interrupts are pending. See:
 the register summary in Table 10-27 on page 153 for the register attributes
 Table 10-28 on page 154 for which interrupts are controlled by each register.
The bit assignments are:
• SETPEND
Interrupt set-pending bits.
Write:
0: no effect.
1: changes interrupt state to pending.
Read:
0: interrupt is not pending.
1: interrupt is pending.
Writing 1 to the ISPR bit corresponding to:
• an interrupt that is pending has no effect
• a disabled interrupt sets the state of that interrupt to pending
