ATA5823/ATA5824
The timing of the FD mode is illustrated in
place if the FD mode is enabled in the slave before it is enabled in the master. If the FD mode is
enabled in the master before it is enabled in the slave, a maximum delay T
proper operation. T
during the Bit-check. This is calculated as follows:
T
Table 14-7.
This means, to get a extended time period for enabling the FD mode, increase the preburst
length in the master and reduce N
sampling edge (pin SCK) for the LSB while writing control register 1.
For a proper operation in the slave, a wake-up due to noise must be prevent (bit check + start bit
ok). To achieve this for the slave the following adjustments are recommended:
FD_sync
1. Set N
2. Start FD mode in master and slave as simultaneously as possible.
