5.6.2
5.6.2.1
The function i2c_init configures the I
transaction in the transaction queue.
FIGURE 5-1:
5.6.2.2
The function i2c_insert places one complete set of transaction request block (trb’s).
TRBs can be bundled into an array of multiple TRBs and inserted as one large request.
The driver will ensure that all the TRBs in the list will be processed sequentially with I
restarts separating them.
FIGURE 5-2:
5.6.2.3
The i2c_build_write_trb and i2c_build_read_trb functions are helpers to
assemble the I2C_TRANSACTION_REQUEST_BLOCKS from passed parameters.
FIGURE 5-3:
5.6.2.4
The i2c_write_block and i2c_read_block functions are helpers that assemble
a TRB, insert it into the queue and wait for the transaction to complete.
