Transmission buffer
TBF is a 33-byte FIFO buffer used to hold the number of bytes of transmission data and transmission data for master
transmission and slave data transmission.
TBF can be written from the microcomputer when the TFL flag of the STR register is set to 0 (indicating that TBF
is not full).
In master transmission and slave data transmission, the following format is used to load data into TBF from the
microcomputer.
[Byte 1]
: Number of bytes of transmission data
Between 1 and 256 bytes can be set.
[Bytes 2 and up]
: Transmission data
As much transmission data as is set in byte 1 is set in byte 2 and subsequent bytes.
Byte 1
Number of bytes of transmission data
Byte 2
First byte of transmission data
Byte 3
Second byte of transmission data
