$34B (preset: $34B 000)
The low frequency can be boosted for brake operation.
See "§ 5-12 for brake operation".
SFBK1: When 1, brake operation is performed by setting the LowBooster-1 input to 0.
This is valid only when TLB1ON = 1. The preset is 0.
SFBK2: When 1, brake operation is performed by setting the LowBooster-2 input to 0.
This is valid only when TLB2ON = 1. The preset is 0.

$34C (preset: $34C 000)
These commands turn on the boost function. (See "§ 5-20. Filter Composition".)
There are five boosters (three for the TRK filter and two for the FCS filter) which can be turned on and off
independently.
THBON: When 1, the high frequency is boosted for the TRK filter. Preset when 0.
FHBON: When 1, the high frequency is boosted for the FCS filter. Preset when 0.
TLB1ON: When 1, the low frequency is boosted for the TRK filter. Preset when 0.
FLB1ON: When 1, the low frequency is boosted for the FCS filter. Preset when 0.
TLB2ON: When 1, the low frequency is boosted for the TRK filter. Preset when 0.
The difference between TLB1ON and TLB2ON is the position where the low frequency is boosted.
For TLB1ON, the low frequency is boosted before the TRK jump, and for TLB2ON, after the TRK jump.
The following commands set the boosters. (See "§ 5-20. Filter Composition".)
HBST1, HBST0: TRK and FCS HighBooster setting.
HighBooster has the configuration shown in Fig. 5-24a, and can select three different
combinations of coefficients BK1, BK2 and BK3. (See Table 5-25a.)
An example of characteristics is shown in Fig. 5-26a.
These characteristics are the same for both the TRK and FCS filters.
The sampling frequency is 88.2kHz (when MCK = 128Fs).
LB1S1, LB1S0: TRK and FCS LowBooster-1 setting.
LowBooster-1 has the configuration shown in Fig. 5-24b, and can select three different
combinations of coefficients BK4, BK5 and BK6. (See Table 5-25b.)
An example of characteristics is shown in Fig. 5-26b.
These characteristics are the same for both the TRK and FCS filters.
The sampling frequency is 88.2kHz (when MCK = 128Fs).
LB2S1, LB2S0: TRK LowBooster-2 setting.
LowBooster-2 has the configuration shown in Fig. 5-24c, and can select three different
combinations of coefficients BK7, BK8 and BK9. (See Table 5-25c.)
An example of characteristics is shown in Fig. 5-26c.
This booster is used exclusively for the TRK filter.
The sampling frequency is 88.2kHz (when MCK = 128Fs).
Note)
Fs = 44.1kHz
