11.4.1.7.3 Interrupt Enable Set Registers (IESR, IESRH)
The interrupt enable set registers (IESR/IESRH) are used to enable interrupts. Writes of 1 to the bits in
IESR/IESRH set the corresponding interrupt bits in the interrupt enable registers (IER/IERH); writes of 0
have no effect.
The IESR is shown in Figure 11-92 and described in Table 11-76. The IESRH is shown in Figure 11-93
and described in Table 11-77.
