Description
If an FSK interrupt has occurred and no FSK error is detected, the FSK data register
contains valid data.
Description
POL1 = 0: voltage on input POL1 < V
POL0 = 0: voltage on input POL0 > V
LOW-BAT Indication = 1: voltage on input LOWBAT < V
FSK-BOM Indication = 1: begin of mark period detected
FSK-OVR Error = 0: no FSK overrun error;
FSK-OVR Error = 1: FSK overrun error, data byte(s) lost
FSK-FRM Error = 0: no FSK frame error;
FSK-FRM Error = 1: FSK frame error, stop bit was wrong
reserved bits
Description
The value held in this byte denotes the time between two positive edges of the POL1
comparator output (between two positive edges of POL1 one positive edge of POL0
must have been detected).
