The following bits are involved:
For details about the DC’s interrupt logic, see
When the ISP1161A1’s DC enters the ‘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
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

CLKRUN switches the oscillator on and off
CLKDIV[3:0] is the division factor determining the normal CLKOUT frequency
NOLAZY controls the LazyClock signal output during ‘suspend’ state.
