CS5368
5. REGISTER MAP
In Control Port Mode, the bits in these registers are used to control all of the programmable features of the ADC. All
registers above 0Ah are RESERVED.
5.1 Register Quick Reference
5.2 00h (REVI) Chip ID Code & Revision Register
Default: See description
The Chip ID Code & Revision Register is used to store the ID and revision of the chip.
Bits[7:4] contain the chip ID, where the CS5368 is represented with a value of 0x8.
Bits[3:0] contain the revision of the chip, where revision A is represented as 0x0, revision B is represented
as 0x1, etc.
5.3 01h (GCTL) Global Mode Control Register
Default: 0x00
The Global Mode Control Register is used to control the Master/Slave Speed modes, the serial audio data
format and the Master clock dividers for all channels. It also contains a Control Port enable bit.
Bit[7] CP-EN manages the Control Port Mode. Until this bit is asserted, all pins behave as if in Stand-Alone
Mode. When this bit is asserted, all pins used in Stand-Alone Mode are ignored, and the corresponding reg-
ister values become functional.
Bit[6] CLKMODE Setting this bit puts the part in 384X mode (divides XTI by 1.5), and clearing the bit in-
vokes 256X mode (divide XTI by 1.0 - pass through).
