Page Selection

These bits are used to select one of three register pages for write and/or read access through the SPI or I2C serial host interface. The

Page Selection Register is present on every register page at address 0x7F, allowing movement between pages as necessary.

9.5.3 Channel Status and User Data Buffer Maps

Table 35 through Table 38 show the buffer maps for the DIR and DIT channel status and user data buffers.

For Table 35, the channel status byte definitions are dependent on the transmission mode, either Professional or

Consumer. Bit 0 of Byte 0 defines the transmission mode, 0 for Consumer mode, and 1 for Professional mode.

This is applicable for Table 35 and Table 36.

For Table 37, the channel status byte definitions are dependent on the transmission mode, either Professional or

Consumer. Bit 0 of Byte 0 defines the transmission mode, 0 for Consumer mode, and 1 for Professional mode. In

Professional mode, Byte 23 for each channel is reserved for CRC data, which is automatically calculated and

encoded by the DIT. There is no requirement to program Byte 23 for either channel in Professional mode.
