#
(e) Program OSR value
#
# DOSR = 128, DOSR(9:8) = 0, DOSR(7:0) = 128
w 30 0D 00 80
#
(f) Program I2S word length if required (16, 20, 24, 32 bits)
#
and master mode (BCLK and WCLK are outputs)
#
# mode is i2s, wordlength is 16, slave mode
w 30 1B 00
#
(g) Program the processing block to be used
#
# Select Processing Block PRB_P11
w 30 3C 0B
w 30 00 08
w 30 01 04
w 30 00 00
#
(h) Miscellaneous page 0 controls
#
# DAC => volume control thru pin disable
w 30 74 00
# 3. Program analog blocks
#
(a) Set register page to 1
#
w 30 00 01
#
(b) Program common-mode voltage (defalut = 1.35 V)
#
w 30 1F 04
#
(c) Program headphone-specific depop settings (in case headphone driver is used)
#
# De-pop, Power on = 800 ms, Step time = 4 ms
w 30 21 4E
#
(d) Program routing of DAC output to the output amplifier (headphone/lineout or speaker)
#
# LDAC routed to HPL out, RDAC routed to HPR out
w 30 23 44
#
(e) Unmute and set gain of output driver
#
# Unmute HPL, set gain = 0 db
w 30 28 06
# Unmute HPR, set gain = 0 dB
w 30 29 06
# Unmute Class-D Left, set gain = 18 dB
w 30 2A 1C
# Unmute Class-D Right, set gain = 18 dB
w 30 2B 1C
#
(f) Power up output drivers
#
# HPL and HPR powered up
w 30 1F C2
# Power-up Class-D drivers
w 30 20 C6
# Enable HPL output analog volume, set = -9 dB
w 30 24 92
# Enable HPR output analog volume, set = -9 dB
w 30 25 92
# Enable Class-D Left output analog volume, set = -9 dB
w 30 26 92
# Enable Class-D Right output analog volume, set = -9 dB
w 30 27 92
#
# 4. Apply waiting time determined by the de-pop settings and the soft-stepping settings
#
of the driver gain or poll page 1 / register 63
#
# 5. Power up DAC
