Interrupt Mask Register
Each interrupt source can generate an interrupt signal on port INT
(characteristics of the output stage are defined via register IPC). A ‘1’
in a bit position of IMR0 ... 4sets the mask active for the interrupt
status in ISR0 ... 4. Masked interrupt statuses neither generate a
signal on INT, nor are they visible in registers GIS or CIS . Moreover,
they will
– not be displayed in the Interrupt Status Register if bit GCR.VIS is
– be displayed in the Interrupt Status Register if bit GCR.VIS is set to
Note: After RESET, all interrupts are disabled.
