Table 96. Register 0x60Normal Mode Digital Filter LF Gain Setting
Bits Bit Name R/W Description
[7:0] LF gain setting R/W This register determines the low frequency gain of the loop response in normal mode. The LF gain
is programmable over a 20 dB range (see Figure 58).
Table 97. Register 0x61Normal Mode Digital Filter Zero Setting
Bits Bit Name R/W Description
[7:0] Zero setting R/W This register determines the position of the final zero in normal mode (see Figure 58).
Table 98. Register 0x62Normal Mode Digital Filter Pole Setting
Bits Bit Name R/W Description
[7:0] Pole location R/W This register determines the position of the final pole in normal mode (see Figure 58).
Table 99. Register 0x63Normal Mode Digital Filter HF Gain Setting
Bits Bit Name R/W Description
[7:0] HF gain setting R/W This register determines the high frequency gain of the loop response in normal mode. The HF
gain is programmable over a 20 dB range (see Figure 58).
