Function
Example: Enabling the INT0 interrupt
All interrupt sources other than those used for STOP/SLEEP wake-up signaling are controlled by the
INTC block.
Note 1:
Note 2:
IMCGA0.EMCG[01:00] = 10
IMCGA0.INT0EN = 1
IMC0L.EIM[11:10] = 01
IMC0L.IL[12:10] = 101
Clearing the INT0-INT4 and INTRTC interrupt requests, if programmed for STOP/SLEEP wake-
up signaling, requires two register settings: first, the EICRCG register in the CG block, and
then the INTCLR register in the INTC block. The clearing of other interrupt sources is
controlled through the INTCLR register alone.
In cases where INT0-INT4 are not used for STOP/SLEEP wake-up signaling, they are controlled
by the INTC block in the same way as other interrupt sources. INTRTC is controlled by both
the CG and INTC blocks, regardless of whether it is used for wake-up signaling.
