Bits[5:4] MDIV[1:0] Each bit selects an XTI divider. When either bit is low, an XTI divide-by-1 function is

selected. When either bit is HIGH, an XTI divide-by-2 function is selected. With both bits HIGH, XTI is divid-

ed by 4.

The table below shows the composite XTI division using both CLKMODE and MDIV[1:0].

Bits[3:2] DIF[1:0] Determine which data format the serial audio interface is using to clock-out data.

0x00 Left-Justified format

0x01 I²S format

0x02 TDM

0x03 Reserved

Bits[1:0] MODE[1:0] This bit field determines the device sample rate range and whether it is operating as

an audio clocking Master or Slave.

MODE[1:0]

0x00 Single-Speed Mode Master

0x01 Double-Speed Mode Master

0x02 Quad-Speed Mode Master

0x03 Slave Mode all speeds

02h (OVFL) Overflow Status Register

Default: 0xFF, no overflows have occurred.

Note:

This register interacts with Register 03h, the Overflow Mask Register.

The Overflow Status Register is used to indicate an individual overflow in a channel. If an overflow condition

on any channel is detected, the corresponding bit in this register is asserted (low) in addition to the open

drain active low OVFL pin going low. Each overflow status bit is sticky and is cleared only when read, pro-

viding full interrupt capability.

5.5

03h (OVFM) Overflow Mask Register

Default: 0xFF, all overflow interrupts enabled.

The Overflow Mask Register is used to allow or prevent individual channel overflow events from creating

activity on the OVFL pin. When a particular bit is set low in the Mask register, the corresponding overflow

bit in the Overflow Status register is prevented from causing any activity on the OVFL pin.
