LC89052TA-E SANYO [Sanyo Semicon Device], LC89052TA-E Datasheet - Page 39

• Manufacturer Part Number: LC89052TA-E
• Description: Digital Audio Interface Receiver
• Manufacturer: SANYO [Sanyo Semicon Device]

• The error information, non-PCM information, input fs calculation result, and channel status data can be read from this
• The input data fs calculation results are allocated as follows. The target calculation frequency differs depending on the
• The first 48 bits of channel status can be read.
• Since the channel status consists of 192 frames, updated data can always be read by reading at the interval 192 times
• It is also possible to read by using the updated flag of the interrupt source and setting E/INT to interrupt output to

reduce the load of the microcontroller. This flag is output when the first 48 bits of the current data is compared with
the data of the previous block and found that those data are identical.
