Clocks
Interrupts
Debug Operation
The clock for the TWIM bus interface (CLK_TWIM) is generated by the Power Manager. This
clock is enabled at reset, and can be disabled in the Power Manager. It is recommended to
disable the TWIM before disabling the clock, to avoid freezing the TWIM in an undefined state.
The TWIM interrupt request lines are connected to the interrupt controller. Using the TWIM
interrupts requires the interrupt controller to be programmed first.
When an external debugger forces the CPU into debug mode, the TWIM continues normal
operation. If the TWIM is configured in a way that requires it to be periodically serviced by the
CPU through interrupts or similar, improper operation or data loss may result during
debugging.
