Operation Mode
Operation and Communication Modes of CircLink
TMC2072 supports only Peripheral mode, meaning communications require an external CPU. TMC2072
does not support standalone mode, which enables communications without a CPU.
There are two communication modes in Peripheral mode: Free-format mode which is capable of handling a
free-format packet, and Remote Buffer mode, which uses CircLink as a simple buffer. Register bits RXM01
to 31 specify the RX mode of each page and TXM specifies the mode for TX mode.
Operation Mode
Peripheral mode
Peripheral mode acts as the CPU's peripheral circuit and has two communication modes, Free-format
mode and Remote Buffer mode. The communication mode is independently selectable for send and
receive; TXM of the Mode register for sender and RXM01 to RXM31 of the Receive Mode register for
receive. The communication mode for sender and receiver must be identical and the communication mode
of the receiver page should be adjusted to the communication mode of the sender.
Note: TMC2072 does not support standalone mode.
