R260 (0104h) Sample rate 3 4:0 SAMPLE_RATE_ 3 [4:0] 10001 Sample Rate 3 Select Register coding is same as SAMPLE_RATE_1. R266 (010Ah) Sample rate 1 status 4:0 SAMPLE_RATE_ 1_STS [4:0] 00000 Sample Rate 1 Status (Read only) Register coding is same as SAMPLE_RATE_1. R267 (010Bh) Sample rate 2 status 4:0 SAMPLE_RATE_ 2_STS [4:0] 00000 Sample Rate 2 Status (Read only) Register coding is same as SAMPLE_RATE_1. R268 (010Ch) Sample rate 3 status 4:0 SAMPLE_RATE_ 3_STS [4:0] 00000 Sample Rate 3 Status (Read only) Register coding is same as SAMPLE_RATE_1. R274 (0112h) Async clock 1 10:8 ASYNC_CLK_FR EQ [2:0] 011 ASYNCCLK Frequency 000 = 6.144MHz (5.6448MHz) 001 = 12.288MHz (11.2896MHz) 010 = 24.576MHz (22.5792MHz) 011 = 49.152MHz (45.1584MHz) All other codes are Reserved The frequencies in brackets apply for 44.1kHz-related sample rates only (ie. ASYNC_SAMPLE_RATE_n = 01XXX). 6 ASYNC_CLK_EN A 0 ASYNCCLK Control 0 = Disabled 1 = Enabled ASYNCCLK should only be enabled after the applicable clock source has been configured and enabled. Set this bit to 0 when reconfiguring the clock sources. |
