Structure of the Output Data

1. The output data consists of a total of 288 bits (36 bytes). The first two bytes are status information.

2. CNT1 and CNT2 are both output LSB first.

3. Corrected data is output in order starting with the first bit in each block.

4. The BIC code is not output.

5. These points hold for both serial and parallel mode.

*: The CPU can easily select data by first checking the content of the status information when data is read out. Data that

is not required does not have to be read; rather, the CPU can cancel the remainder of the readout operation. (The

CPU can simply ignore data until the next interrupt.)

288 bits (36 bytes)

Corrected data

272 bits (34 bytes)

*Bits 0 and 1 are unused and contain invalid data.

First block data output (Only when VH is low.)

However, this bit is only valid when only horizontal correction is applied, i.e.

when VH = 0.

Normal data

Parity data

Correction OK

Error (uncorrectable data)

Indicates data for which frame synchronization was not achieved

Indicates frame synchronized data

Indicates data for which block synchronization was not achieved

Indicates block synchronized data

Output that was only corrected horizontally (synchronized output)

Output that was vertically corrected

BLN7 to BLN0: Expresses the block number or the parity block number of the output data. The block numbers within a

single frame range from 0 to 189, and the parity block numbers from 0 to 81.

Note that parity block data is not output for vertically corrected data.

No. 4870-7/14
