DSSN going active is delayed 8 bit times from INT
DSSN is immediately active after INT
System clock outputs 1024 clock cycles before shutdown after idle command
System clock outputs 512 clock cycles before shutdown after idle command
System clock outputs 256 clock cycles before shutdown after idle command
System clock immediately shuts down after idle command
Periodic housekeeping enabled (HK settings must be set)

Force the receiver to not output Clk&Data < energy level
0
Set the receiver to wake when at energy level threshold
2
Enable periodic Sniff Mode
The quick start technology enables the AMIS-53000 to operate its receiver in a mode called Sniff Mode. As implemented in the
AMIS-53000, this Sniff Mode can wake the receiver and acquire the transmitted message in as little as 130 microseconds.
