6.9.15.1.4 Low-Power Mode Wakeup Timing
Table 6-68 shows the timing requirements, Table 6-69 shows the switching characteristics, and Figure 6-
50 shows the timing diagram for IDLE mode.

(2) This is the time taken to begin execution of the instruction that immediately follows the IDLE instruction. execution of an ISR (triggered
by the wake-up) signal involves additional latency.

WAKE INT^(A)(B)
t_{w(WAKE−INT)}
A. WAKE INT can be any enabled interrupt, WDINT or XRS. After the IDLE instruction is executed, a delay of 5
OSCCLK cycles (minimum) is needed before the wake-up signal could be asserted.
B. From the time the IDLE instruction is executed to place the device into low-power mode (LPM), wakeup should not be
initiated until at least 4 OSCCLK cycles have elapsed.
