PRELIMINARY INFORMATION AUG 02, 2011
Table 6.10.4.1: I²C Module Registers
Receive Data FIFO Registers
The data received from the master is stored in the receive fifo registers and has a depth of 4. The current fill
level can be read in the status register. If the fifo is completely filled up and another byte should be received
the interface will force the master into a wait state until the application software reads one byte from the fifo.
Register Receive Data FIFO Register (0x00)
Table 6.10.5.1: Receive Data FIFO Register
Send Registers:
The master reads data that is stored in the send fifo registers. This fifo buffer has a depth of 4 registers. The
current fill level can be read in the status register. If the fifo is empty and a byte is requested by the master
the interface will force the master into a wait state until the application software writes one byte to the fifo.
