When the data area or empty area exceed the above stage number, FIFO capacity always can be
used 16 stages. Therefore, over flow or under flow error are submitted when the data area, or
empty area excesses 16 stages.
Even if FIFO is not empty or full, the transmit request is cancelled when the above conditions
become not to be satisfied.
(3) Showing of Stage Number
The state of using transmit or receive FIFO is displayed in the following registers.
• Transmit FIFO: Shows stage number of empty area to bits TFUA4 to TFUA0 in SIFCTR
• Receive FIFO: Shows stage number of effective data to bits RFUA4 to RFUA0 of SIFCTR
The above contents show the number of data which CPU or DMAC can transfer.
