SPIRX data register overflow status bit
Set if SPIRX is overflowing
Cleared by reading SPISRX register
SPIRX data register IRQ
Set automatically if bit 3 or 5 are set
Cleared by reading SPIRX register
SPIRX data register full status bit
Set automatically if a valid data is present in the SPIRX register
Cleared by reading SPIRX register
SPITX data register underflow status bit
Set automatically if SPITX is under flowing
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 writing in the SPITX register or if finished transmission 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
