CHAPTER 16 MANCHESTER CODE GENERATOR
16.1 Functions of Manchester Code Generator
The following three types of modes are available for the Manchester code generator.
(1) Operation stop mode
This mode is used when output by the Manchester code generator/bit sequential buffer is not performed. This
mode reduces the power consumption.
For details, refer to 16.4.1 Operation stop mode.
(2) Manchester code generator mode
This mode is used to transmit Manchester code from the MCGO pin.
The transfer bit length can be set and transfers of various bit lengths are enabled. Also, the output level of the
data transfer and LSB- or MSB-first can be set for 8-bit transfer data.
(3) Bit sequential buffer mode
This mode is used to transmit bit sequential data from the MCGO pin.
The transfer bit length can be set and transfers of various bit lengths are enabled. Also, the output level of the
data transfer and LSB- or MSB-first can be set for 8-bit transfer data.
