RPS_RE0
26
R
RPS Task 0 Register access Error: this bit is set when the LDREG,
STREG or MASKWRITE command tries to access a non-existing
register. This bit is reset by writing a logic 1 to the RPS_E0 bit in the ISR
or when a new RPS Task 0 is started.
RPS_PE0
25
R
RPS Task 0 Page Error: this bit is set when the RPS Task 0 tries to
write-access an address outside the 4-kbyte page. This bit is reset by
writing a logic 1 to the RPS_E0 bit in the ISR or when a new RPS Task 0
is started.
RPS_A0

R
R
RPS Task 0 Active: this bit is set whenever RPS Task 0 is executing
and not staying in a wait condition or uploading the working registers
DEBI_TO
DEBI Time Out: this bit is set when the TIMEOUT value was reached.
This bit is reset by writing a logic 1 to the DEBI_E bit in the ISR. Reset
value is a logic 1.

DEBI Format Error: this bit indicates an illegal command to immediate
transfer across a Dword boundary. This bit is reset by writing a logic 1 to
the DEBI_E bit in the ISR.
I2C-bus Address Error: this bit is set when there is no acknowledge
after the device address. This bit is reset by writing a logic 1 to the IIC_E
bit in the ISR or when a new I2C-bus command starts.
I2C-bus Write data Error: this bit is set when there is no acknowledge
during the writing of the data byte(s). This bit is reset by writing a logic 1
to the IIC_E bit in the ISR or when a new I2C-bus command starts.
I2C-bus Read data Error This bit is set when there is no acknowledge
during reading of the data byte(s). This bit is reset by writing a logic 1 to
the IIC_E bit in the ISR or when a new I2C-bus command starts.
I2C-bus Loss arbitration Error: this bit is set when the I2C-bus loses its
arbitration. This bit is reset by writing a logic 1 to the IIC_E bit in the ISR
or when a new I2C-bus command starts.
I2C-bus Frame Error: this bit is set when there is an invalid
START/STOP condition since the last I2C-bus command. This bit is
reset by writing a logic 1 to the IIC_E bit in the ISR or when a new
I2C-bus command starts.

Video DMA 3 Protection error: this bit is set when video DMA3
generates an address during an active transmission beyond its
protection address. This bit is reset by writing a logic 1 to the V_PE bit in
the ISR or by reloading the DMA base address.
Video DMA 2 Protection error: this bit is set when video DMA2
generates an address during an active transmission beyond its
protection address. This bit is reset by writing a logic 1 to the V_PE bit in
the ISR or by reloading the DMA base address.
Video DMA 1 Protection error: this bit is set when video DMA1
generates an address during an active transmission beyond its
protection address. This bit is reset by writing a logic 1 to the V_PE bit in
the ISR or by reloading the DMA base address.
Video FIFO 3 underflow/overflow: this bit is set when the video FIFO 3
has an overflow/underflow. This bit is reset when reloading the DMA
base address or by writing a logic 1 to the VFOU bit in the ISR.
