C-bus interface
The USB function has its own I
2
C-bus interface for communication with the microcontroller. The I
2
C-bus uses two
addresses:
Command address for writing commands to the Memory Manager (MM)
Data address for writing/reading data to/from the Memory Manager (MM).
An address is a byte. The 7 MSBs are the actual address, the LSB is the R/W bit. When it is logic 0, data is transferred
from the master to the slave, when it is logic 1, data is written from the slave to the master.
The 6 MSBs of the two addresses are equal and are defined by the PI_Address = 010111 (see Table 58). The LSB of
the address differentiates between the command address and the data address. When bit 1 is logic 1 the address is the
command address (0x5E) and when bit 1 is logic 0 the address is one of the data addresses (0x5C or 0x5D).
