at a time. The tuner doesn't like it when the i2c resets to send the 5th
|
||
|
|
byte. So, we can only read/write the first 4 bytes. Luckily, on read,
|
||
|
|
the 5th byte is reserved and on write we only use that for the deemphasis
|
||
|
|
bit (which we'll have to ignore). This is what the OF appears to do too. */
