6. REGISTER DESCRIPTION
All registers are read/write except for the I.D. and Revision Register, OMCK/PLL_CLK Ratio Register, Interrupt Sta-
tus Register, and Q-Channel Subcode Bytes and C-bit or U-bit Data Buffer, which are read only. See the following
bit definition tables for bit assignment information. The default state of each bit after a power-up sequence or reset
is listed in each bit description.
6.1 Memory Address Pointer (MAP)
Not a register
6.1.1 INCREMENT (INCR)
Default = 1
Function:
Memory Address Pointer auto increment control
0 - MAP is not incremented automatically.
1 - Internal MAP is automatically incremented after each read or write.
6.1.2 MEMORY ADDRESS POINTER (MAPX)
Default = 0000001
Function:
Memory Address Pointer (MAP). Sets the register address that will be read or written by the control
port.
6.2 Chip I.D. and Revision Register (address 01h) (Read Only)
6.2.1 CHIP I.D. (CHIP_IDX)
Default = 1110
Function:
I.D. code for the CS42516. Permanently set to 1110.
6.2.2 CHIP REVISION (REV_IDX)
Default = xxxx
Function:
CS42516 revision level.
Revision D is coded as 0100.
Revision C is coded as 0011.
