Access :
Read Only
Function :
The 8-bit MMR represents the current status of the Serial Peripheral Interface.
Table 80 : SPISTA MMR Bit Descriptions
Bit
Description
7-6
Reserved
5
SPIRX data register overflow status bit
Set if SPIRX is overflowing
Cleared by reading SPISRX register
4
SPIRX data register IRQ
Set automatically if bit 3 or 5 are set
Cleared by reading SPIRX register
3
SPIRX data register full status bit
Set automatically if a valid data is present in the SPIRX register
Cleared by reading SPIRX register
2
SPITX data register underflow status bit
Set automatically if SPITX is under flowing
Cleared by writing in the SPITX register
1
SPITX data register IRQ
Set automatically if bit 0 is clear or bit 2 is set
Cleared by writing in the SPITX register or if finished transmission disabling the SPI
0
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
via the Serial Peripheral Interface.
SPI Transmit Register :
Name :
SPITX
Address :
0xFFFF0A08
Default Value :
0x00
Access :
Write Only
Function :
This 8-bit MMR is written to, to transmit
data via 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 of
the Serial Peripheral Interface is operating at. For more
information on the calculation of the baud rate, please refer to
Equation 3 : SPI Baud Rate Calculation.
