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

• NACK returned

after own slave

address received

• in addressed

mode, data are

transmitted on a

multiple byte basis

= BC[6:0] value

• in addressed

mode, switch to

non addressed

mode after the last

byte of a buffered

sequence is

transmitted (after

bytes sent

= BC[6:0] value)

Slave Receiver mode

• NACK 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)

• in addressed mode,

switch to non-addressed

mode after the last byte of

a buffered sequence is

received (after bytes

received = BC[6:0] value)

Slave Transmitter mode

• NACK returned after

own slave address

received

• in addressed mode,

data are transmitted

on a multiple byte

basis = BC[6:0]

value

• in addressed mode,

switch to non

addressed mode

after the last byte of

a buffered

sequence is

transmitted (after

bytes sent = BC[6:0]

value)

Slave Receiver mode

• NACK returned after

own slave address

received

• in addressed mode, data

are received on a

multiple byte basis

= BC[6:0] value

• in addressed mode,

NACK returned after the

last byte of a buffered

sequence received (after

bytes received = BC[6:0]

value)

• in addressed mode,

switch to non-addressed

mode after the last byte

of a buffered sequence

is received (after bytes

received = BC[6:0]

value)
