Relationship of M8051 SFR Register Map With I2C Registers RST: Module reset 0: Normal operation 1: Reset SPDIF-TX module (default) CP: Copy permit 0: Copy prohibit (default) 1: Copy permit EMP: Pre-emphasis 0: No pre-emphasis (default) 1: 50/15 s 2-channel pre-emphasis CATEGORY: Category code 7-bit device category code. Default: 0101010 (digital sound processor) L: Generation status 0: Generation 1 or higher (default) 1: Original SR: Sampling rate 00: 44.1 kHz 01: 48 kHz (default) 10: Reserved 11: 32 kHz VL: Validity for left channel 0: Left channel data is valid (default) 1: Left channel data is invalid VR: Validity for right channel 0: Right channel data is valid (default) 1: Right channel data is invalid SRCNUM: Source channel number 0000: Not specified 0001: 1 0010: 2 (default) 0011: 3 . . . 1000: 8 CLKAC: Clock accuracy 00: Level II, 1000 ppm 01: Level III, variable pitch shifted 10: Level I, 50 ppm (default) 11: Reserved WORDLEN: Sample bit size 0000: 24 bits (default) 0001: 23 bits 0010: 22 bits . . . 20 bits 0100: . . . 1000: 16 bits Others: Reserved I2C Register Map for SPDIF Figure 15 shows system accessible I2C register mapping for controlling the SPDIF module. The mute control (MTE) uses the same control bits for controlling SDOUT2 mute at subaddress 0x09 and the module reset (RST) is mapped to subaddress 0x10 together with other power down control bits. Other control bits are mapped to subaddress 0x16. 18 Submit Documentation Feedback Copyright © 2008, Texas Instruments Incorporated Product Folder Link(s): TAS3218 |
