10.4.7 Register Write Access
To write data from the host controller via I
following frame format shall be used.
The first byte of a frame indicates the device address according to the I
second byte indicates the register address followed by up to n-data bytes. In one frame all
n-data bytes are written to the same register address. This enables for example a fast
FIFO access.
The read/write bit shall be set to logic 0.
