If a command is written to the CMR register during communication, how long a wait is required until that command is executed?
A1 When a command is written to the CMR register during communication, the register is overwritten, but the command execution will be put on hold until the end of the current communication. Therefore, a wait of up to 1 frame is required until command execution. For example, the wait of 15.2 ms is required in the case of mode 1.
