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
and described in
. The IESRH is shown in
and described in
