Fig 47. Oscillator and LazyClock logic.
Fig 48. CLKOUT signal timing at ‘suspend’ and ‘resume’ for DC.
If enabled, the 100 ± 50 % kHz LazyClock frequency will be output on pin CLKOUT during ‘suspend’ state.

SUSPEND
When ISP1161A’s DC enters ‘suspend’ state (by setting and clearing bit GOSUSP in
the DcMode register), outputs D_SUSPEND and CLKOUT change state after
approximately 2 ms delay. When NOLAZY = 0 the clock signal on output CLKOUT
does not stop, but changes to the 100 kHz ± 50 % LazyClock frequency.
When resuming from ‘suspend’ state by a positive pulse on input D_WAKEUP, output
SUSPEND is cleared and the clock signal on CLKOUT restarted after a 0.5 ms delay.
The timing of the CLKOUT signal at ‘suspend’ and ‘resume’ is given in
1.8 to 2.2 ms
