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 clear or Bit 2 is set.
Cleared by either writing in the SPITX register or, if
finished transmission, 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.
