Note 1:
DA_DEEMPHASIS [1:0] have following truth-table: ‘00’ = No emphasis, ‘01’ = 50-15 ms emphasis, ‘10’ = Reserved, ‘11’ =
CCITT J.17
DA_SURMOD[1:0] used to indicate whether Dolby Digital encoded stream has been encoded in Dolby Surround.
DA_LR_CH_CLK (via GP19) is a clock whose phase indicates the presence of left hand or right hand data, and whose rate is
equivalent to fs. Signal routed through to GP14 (not bonded out).
GP00 and GP01 inputs are Latched during Power-up only. Active Low Input at power-up to enable Boot Mode functions.
GP03 and GP17 inputs are Latched at Power-up only.
GP29 XPT_PWM_OUTPUT Compensates for frequency errors in 27MHz external VCXO.

6.11 Simplified General Purpose Input Output Interface
The Simplified General Purpose Input Output Interface is provided with 8 pins that can be configured as general
purpose I/O bits. As there is only one mapped SGPIO signal mapped to each of the pins, the interface is simple,
with SGPIO inputs monitored using the SGPI input register, and outputs set using the SGPO register.
The Reserved signals are configured as “Big Endian”. This means that DV1_DATA [0] is the Most Significant Bit
(MSB).
