I
This allows the control of the slave I
writing to an EEPROM, or for control of any other I
If 'manual_mode' is set, then the SCL/SDA lines can be bit bashed by writing direct to 'sda'
and 'scl'. Otherwise these are controlled automatically. The 'clk_div' reg is used to slow
down the clock if necessary (default is zero which should result in approx 400 kHz SCL).
The 'start' bit will generate an I2C start bus condition when set high.
The 'cmd_processed' bit will initially be set low and then go high when the command is
complete.
The 'stop' bit will generate an I
will initially be set low and then go high when the command is complete.
The 'read' bit will kick off a read from the current address. The 'cmd_processed' bit will be
set low and then go high when the command is complete. At this point the READ_BYTE
register will contain the data.
If the 'multiple_read' bit is set, then the address will be auto-incremented after each 'read'.
That is, you can kick off another read without first having to set the address.
To write a byte, write the data value into the WRITE_BYTE register, then wait for the
'cmd_processed' bit to go high. Finally check that the 'ack_rx' (acknowledge recieved) bit is
high.
The 'eeprom_present' bit is set by the firmware when it first attempts to address the eeprom.
If it gets an acknowledge then this bit is set high, otherwise it is set low.
