When ISP1181B enters ‘suspend’ state (by setting and clearing bit GOSUSP in the Mode
Register), outputs 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
When resuming from ‘suspend’ state by a positive pulse on input WAKEUP, output
SUSPEND is cleared and the clock signal on CLKOUT is restarted after a 0.5 ms delay.
The timing of the CLKOUT signal at ‘suspend’ and ‘resume’ is given in
SUSPEND
50 % LazyClock frequency will be output on pin CLKOUT during ‘suspend’ state.
