DATA LINK LAYER COMMUNICATION
CONTROL CIRCUIT
The 3874 Group has a built-in data link layer communication con-
trol circuit.
This data link layer communication control circuit is applicable for
multi-master serial bus communication control used only with data
lines through an external driver/receiver.
The data link layer communication control circuit consists of fol-
lowing.
Communication mode register (address 002A
16
)
Transmit control register (address 002B
16
)
Transmit status register (address 002C
16
)
Receive control register (address 002D
16
)
Receive status register (address 002E
16
)
Bus interrupt factor determination control register (address
002F
16
)
Control field select register (address 0030
16
)
Control field data register (address 0031
16
)
Transmit/Receive FIFO (address 0032
16
)
This function is realized by hardware and firmware so that com-
munication protocol can be partially modified according to the
user’s specification.
The following are the standard communication rate and functions
which the data link layer communication control circuit can per-
form.
Communication rate:
Approx. 40 kbps
The communication rate depends on
frame or bit protocol.
Synchronous method:
Half-duplex asynchronous
Modification method:
PWM method, NRZ, etc.
Communication functions:
Bus arbitration
(CSMA/CD method, etc.)
Error detection
(parity, acknowledge, CRC, etc.)
Frame, data retry
The transmission signal is output from the BUS
OUT
pin and input
to the BUS
IN
pin.
Detailed specifications for communication protocol, bit assign-
ment, function, etc. of each register are defined according to each
communication protocol specification confirmation.
