Fm+ parallel bus to I 2 C-bus controller
AA = 1 Master Transmitter
mode
• address/data are
transmitted on a
multiple byte basis
= BC[6:0] value
Master Receiver mode
• address is transmitted
and data are received on
a multiple byte basis
= BC[6:0] value
• ACK returned after the
last byte of a buffered
sequence received (after
bytes received = BC[6:0]
value)
Master Transmitter mode
• address/data are
transmitted on a
multiple byte basis
= BC[6:0] value
Master Receiver mode
• address is transmitted
and data are received on
a multiple byte basis
= BC[6:0] value
• NACK returned after the
last byte of a buffered
sequence received (after
bytes received = BC[6:0]
value)
Slave Transmitter
mode
• ACK returned after
own slave address
received
• in addressed
mode, data are
transmitted on a
multiple byte basis
= BC[6:0] value
• always addressed
during a buffered
sequence
Slave Receiver mode
• ACK returned after own
slave address received
• in addressed mode, data
are received on a multiple
byte basis = BC[6:0]
value
• in addressed mode, ACK
returned after the last
byte of a buffered
sequence received (after
bytes received = BC[6:0]
value)
