The value of Turbo time is deducted based on the hardware comparison of new DAC value in respect to old DAC value, as follows:
If DAC new > DAC old, then TUP = TCDLY
If DAC new < DAC old, and DAC new_divby2 < 21, then TDOWN = TCDLY + TCM * (21 – DAC_new_divby2) If DAC new < DAC old, and
DAC new_divby2 > 21, then TDOWN = TCDLY
If DAC new < DAC old, and DAC new_divby2 = 21, then TDOWN = TCDLY

Bit [3]: DAC Wake−up Control applicable to Wake−up from LP
0 : (default) Don’t apply Turbo when Wake−up from LP STD or LP FTA
1: Always apply Turbo UP when Wake−up from LP STD or LP FTA. Turbo UP is calculated based on DAC value prior to
enter LP STD or LP FTA mode.
NOTE 1: Turbo is NOT applied after Wake−up to the DACs which are programmed with 0x00 in the DAC value register
NOTE 2: Turbo is NOT applied after Wake−up from FTA mode if a trigger (Turbo, Normal, Glide) was generated while TC2x2
was in LP FTA mode
NOTE 3: When Bit[3] = ‘1’, then Turbo is applied after Wake−up regardless if:
• DAC values are updated or not
• last DAC value update is equal with old DAC value
NOTE 4: When RFFE_REG_0x31 / Wake−up DAC Ctrl is ‘0’ (default) Turbo after Wake−Up is applied after first
vhv_too_lowfalling edge is detected. When RFFE_REG_0x31 / Wake−up DAC Ctrl is ‘1’ Turbo after Wake−up is applied
after rc_clk starts.
Bit [2]: Turbo UP latency Select when Wake−up from LP.
This field has no effect when DAC_WAKEUP_CTRL[1:0] = ‘00’
0: (default) Turbo UP latency is 50 ms
1: Turbo UP latency is 100 ms
