0000

BSCC_R4 +

[EXT_BND_SEL_DIV]x256

0000 = [BSCC_R4]

0001 =[BSCC_R4]+256

0010 = [BSCC_R4] + 512

….…

1111 = [BSCC_R4]+3840

NOTE 1. EXT_BND_SEL_DIV are Extra 4 MSBs that extend the Band Select Clock Counter in Register 4. These additional bits are necessary

for band selection to divide down to <500kHz when high PFD frequencies are used.

NOTE 2. BSCC_R4 is the BAND SELECT CLOCK COUNTER value in Register 4.
