IDLE instruction is executed to put the device into HALT mode. B. The PLL block responds to the HALT signal. SYSCLKOUT is held for another 32 cycles before the oscillator is turned off and the CLKIN to the core is stopped. This 32-cycle delay enables the CPU pipe and any other pending operations to flush properly. C. Clocks to the peripherals are turned off and the internal oscillator and PLL are shut down. The device is now in HALT mode and consumes absolute minimum power. D. When XNMI is driven active, the oscillator is turned on; but the PLL is not activated. The pulse duration of 2tc(CI) is applicable when an external oscillator is used. If the internal oscillator is used, the oscillator wake-up time should be added to this parameter. E. When XNMI is deactivated, it initiates the PLL lock sequence, which takes 131,072 X1/XCLKIN cycles. F. When CLKIN to the core is enabled, the device will respond to the interrupt (if enabled), after a latency. The HALT mode is now exited. G. Normal operation resumes. H. XCLKOUT = SYSCLKOUT Figure 8-21.
