#
# The following list gives an example sequence of items that must be executed in the time
# between powering the # device up and reading data from the device. Note that there are
# other valid sequences depending on which features are used.
# 1. Define starting point:
# (a) Power up applicable external hardware power supplies
# (b) Set register page to 0
#
w 30 00 00
#
# (c) Initiate SW reset (PLL is powered off as part of reset)
#
w 30 01 01
#
# 2. Program clock settings
# (a) Program PLL clock dividers P, J, D, R (if PLL is used)
#
# PLL_clkin = MCLK,codec_clkin = PLL_CLK
w 30 04 03
# J = 5
w 30 06 05
# D = 3760, D(13:8) = 0x0E, D(7:0) = 0xB0
w 30 07 0E B0
#
# (b) Power up PLL (if PLL is used)
# PLL Power up, P = 1, R = 1
#
w 30 05 91
#
# (c) Program and power up NDAC
#
# NDAC is powered up and set to 2
w 30 0B 82
#
# (d) Program and power up MDAC

# MDAC is powered up and set to 7
w 30 0C 87
#
# (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, master mode
w 30 1B 0C
# BDIV_CLKIN = DAC_MOD_CLk; BCLK & WCLk active
W 30 1D 05
# BCLK_N = 2
w 30 1E 82
#
# (g) Program the processing block to be used
#
# Select Processing Block PRB_P25
w 30 3C 19
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
# (a) Set register page to 0
#
w 30 00 00
#
# (b) Power up DAC channels and set digital gain
#
# Powerup DAC left and right channels (soft step enabled)
w 30 3F D4
#
# DAC Left gain = -22 dB
w 30 41 D4
# DAC Right gain = -22 dB
w 30 42 D4
#
# (c) Unmute digital volume control
#
# Unmute DAC left and right channels
w 30 40 00
#
# Beep settings
