Delay Select
DLYSEL.
1 = no delay.
0 = 1/2 coarse sample delay.
1-0
Mod Type
MOD(1:0):
00 = QASK.
01 = FM with filtering after modulation (analog FM with baseband filtering provided before
HSP50215). In this mode, both I and Q filters are used.
10 = FM with filtering before modulation (FSK, GMSK). This mode uses only the I filter bank.
11 = not used.

FIFORDY Threshold
RTH(2:0). Programmable FIFO READY Threshold. This digital word represents the FIFO depth
threshold (number of data samples in the FIFO) at which the FIFORDY will be asserted, alerting the
data source that more input data is required in the FIFO. The FIFO threshold sets both the I and Q
FIFO thresholds. RTH2 is the MSB.

IP(1:0). Number of interpolation phases:
00 = not valid.
01 = 4.
