IC SINGLE MASTER BUS INTERFACE (Cont’d)
11.7.5 Low Power Modes
11.7.6 Interrupts
Figure 65. Event Flags and Interrupt Generation
Note: The I2C interrupt events are connected to
the same interrupt vector (see Interrupts chapter).
They generate an interrupt if the corresponding
Enable Control Bit is set and the I-bits in the CC
register are reset (RIM instruction).
Mode
Description
WAIT
No effect on I2C interface.
I2C interrupts cause the device to exit from WAIT mode.
HALT
I2C registers are frozen.
In HALT mode, the I2C interface is inactive and does not acknowledge data on the bus. The I2C interface
resumes operation when the MCU is woken up by an interrupt with “exit from HALT mode” capability.
