Transmit/Receive buffer register
(TB/RB) [Address : 18
16
]
A transmission data is written to or a receive data is read out
from this buffer register.
At writing : a data is written to the Transmit buffer register.
At reading : a content of the Receive buffer register is read out.
5
Note :
A content of the Transmit buffer register cannot be read out.
A data cannot be written to the Receive buffer register.
