(h) Micellaneous page 0 controls
3. Program analog blocks
(a) Set register page to 1
(b) Program common-mode voltage
(c) Program headphone-specific depop settings (in case headphone driver is used)
(d) Program routing of DAC output to the output amplifier (headphone/lineout or speaker)
(e) Unmute and set gain of output drivers
(f) Power up output drivers
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
(b) Power up DAC channels and set digital gain
(c) Unmute digital volume control
A detailed example can be found in Section 5.5.15.
5.5.15 Example Register Setup to Play Digital Data Through DAC and Headphone/Speaker
Outputs
A typical EVM I2C register control script follows to show how to set up the TLV320DAC3101 in playback
mode with fS = 44.1 kHz and MCLK = 11.2896 MHz.
# Key: w 30 XX YY ==> write to I2C address 0x30, to register 0xXX, data 0xYY
#
# ==> comment delimiter
#
# 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 = 8
w 30 06 08
# D = 0000, D(13:8) = 0, D(7:0) = 0
w 30 07 00 00
#
(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 8
w 30 0B 88
#
(d) Program and power up MDAC
#
# MDAC is powered up and set to 2
w 30 0C 82
