(3-1) SPI Status Register (SPIST)
(a) TEMP
(b) TEND
(c) REND
The SPIST register contains three bits that indicates the status of data communication.
(SPITD) contains valid data; otherwise, it is set to “1”.
buffer contains no valid data.
valid transmit data, and also when the transmission is in progress. This bit is set to “1”
after completing the data transmission where the SPITD register and the transmit
FIFO contain no valid data.
and valid data is stored into the receive data register (if there is any valid data). This
bit is cleared to “0” when the receive register (SPIRD) contains no valid data, or when
the reception is in progress.
full with the valid data after completing the reception of the last data. This bit is
cleared to “0” when there is still an empty space of one byte or more in the FIFO.
flag.
For UNIT-mode transmission, this bit is cleared to “0” when the transmit register
For Sequential-mode transmission, this bit is set to “1” when the transmit FIFO
This bit is cleared to “0” when the SPITD register or the transmit FIFO contains
For UNIT-mode reception, this bit is set to “1” when completing the data reception
For Sequential-mode reception, this bit is set to “1” when the 32-byte receive FIFO is
The RFUL flag does not exist because its function is exactly the same as the REND
