The SRC4392 organizes the on-chip registers and data buffers into four pages. The currently active page is

chosen by programming the Page Selection Register to the desired page number. The Page Selection Register

is available on every register page at address 0x7F, allowing easy movement between pages. Table 2 indicates

the page selection corresponding to the Page Selection Register value.

SRC4392. In addition, status registers are provided for flag and error conditions, with many of the status bits

capable of generating an interrupt signal when enabled. See Table 3 for the control and status register map.

buffers correspond to the data contained in the C and U bits of the previously received block of the AES3-

encoded data stream. The contents of these buffers may be read through the SPI or I2C serial host interface and

processed as needed by the host system. See Table 5 for the DIR channel status buffer map, and Table 6 for

the DIR user data buffer map.

buffers correspond to the data contained in the C and U bits of the transmitted AES3-encoded data stream. The

contents of these buffers may be written through the SPI or I2C serial host interface to configure the C and U bits

of the transmitted AES3 data stream. The buffers may also be read for verification by the host system. See

Table 7 for the DIT channel status buffer map, and Table 8 for the DIT user data buffer map.

code. The unlock code remains private; the test modes disable normal operation of the device, and are not

useful in customer applications.

CONTROL REGISTERS

See Table 3 for the control and status register map of the SRC4392. Register addresses 0x00 and 0x34 through

0x7E are reserved for factory or future use. All register addresses are expressed as hexadecimal numbers. The

following pages provide detailed descriptions for each control and status register.
