Field Name
Software Reset (Default: 0)
This field performs SIO resets except for the FIFOs. Setting this bit to “1”
initiates the reset. Set registers are also initialized. This bit returns to “0”
when initialization is complete.
0: Normal operation
1: SIO software reset
Receive FIFO DMA/Interrupt Trigger Level (Default: 00)
This register sets the level for reception data transfer from the Receive
FIFO.

01: 4 Bytes
10: 8 Bytes
11: 12 Bytes
Transmit FIFO DMA/Interrupt Trigger Level (Default: 00)
This register sets the level for transmission data transfer to the Transmit
FIFO.
00: 1 Byte
01: 4 Bytes
10: 8 Bytes
11: Setting disabled
Transmit FIFO Reset (Default: 0)
The Transmit FIFO buffer is reset when this bit is set. This bit is valid when
the FIFO Reset Enable bit (FRSTE) is set. Cancel reset by using the
software to clear this bit.
0: During operation
1: Reset Transmit FIFO
Receive FIFO Reset (Default: 0)
The Receive FIFO buffer is reset when this bit is set. This bit is valid when
the FIFO Reset Enable bit (FRSTE) is set. Cancel reset by using the
software to clear this bit.
0: During operation
1: Reset Receive FIFO
FIFO Reset Enable (Default: 0)
This field is the Reset Enable for the Transmit/Receive FIFO buffer. The
FIFO is reset by combining the Transmit FIFO Reset bit (TFRST) and
Receive FIFO Reset bit (RFRST).
0: During operation
1: Reset Enable
