Description
Reserved.
SPIRX data register overflow status bit.
Set if SPIRX is overflowing.
Cleared by reading the SPIRX register.
SPIRX data register IRQ.
Set automatically if Bit 3 or Bit 5 is set.
Cleared by reading the SPIRX register.
SPIRX data register full status bit.
Set automatically if valid data is present in the SPIRX
register.
Cleared by reading the SPIRX register.
SPITX data register underflow status bit.
Set automatically if SPITX is underflowing.
Cleared by writing in the SPITX register.
SPITX data register IRQ.
Set automatically if Bit 0 is cleared or Bit 2 is set.
Cleared either by writing in the SPITX register or, if the
transmission is finished, by disabling the SPI.
SPITX data register empty status bit.
Set by writing to SPITX to send data. This bit is set
during transmission of data.
Cleared when SPITX is empty.

SPI Receive Register
Name: SPIRX
Address: 0xFFFF0A04
Default Value: 0x00
Access: Read only
Function: This 8-bit MMR contains the data received using the
serial peripheral interface.
SPI Transmit Register
Name: SPITX
Address: 0xFFFF0A08
Access: Write only
Function: Write to this 8-bit MMR to transmit data using the
serial peripheral interface.
SPI Divider Register
Name: SPIDIV
Address: 0xFFFF0A0C
Default Value: 0x1B
Access: Read/write
Function: The 8-bit MMR represents the frequency at which the
serial peripheral interface is operating. For more information
on the calculation of the baud rate, refer to Equation 3.
