1.9ksps Delta-Sigma ADC with PGA
WAIT_EXT (0x0F)
This register extends the count range of the WAIT command.
Wait Clocks = (WAIT_EXT*16) * (WAIT * 16)
For a 2.456MHz clock, the minimum wait period is 6.5µsec. The maximum wait period using the wait extender is 6.77s.
A write to the wait extension will not cause a wait command to execute. Reading this register will return the written value.
When WAIT_EXT = 0x00, no wait extension is applied and the wait period is equal to (WAIT * 16). In the absence of a
reset, the WAIT_EXT selection applies to all subsequent WAIT_START commands.

DESCRIPTION
WAIT_START (0x10)
A write to this register will execute a 'wait' operation with a clock count equal to
Wait Clocks = (WAIT_EXT x 16) * (WAIT x 16)
For a 2.456MHz input clock, the minimum wait period is 6.5µsec. The maximum wait period utilizing the wait extender
is 6.77s.
Reading this register will return the current count value, as decremented since the last WAIT execution. Writing to any
register during a wait will abort the count operation, but will not reset the register. Writing "0x00" to this register will result
in a 'No Op', and no WAIT_DONE status will be issued. If in PD: SLEEP or PD: STANDBY mode, writing to this register
changes the mode to PD: Normal Mode.
