29
AGC_RFOFF_DET_ IRQ
R
0, 1
Set to 1 by hardware, when the AGC has detected the
external RF-Field was switched off while transmitting in
SL-ALM mode.
Note
: Only valid if the detection mode is enabled with the
register bit-field AGC_RF_DETECT_SEL.
28
TX_DATA_REQ_IRQ
R
0*, 1
Set to 1 by hardware, when the Buffer Manager requests
data for transmission from RAM.
Note
: Only valid if the bit DIRECT_DATA_ACCESS_
ENABLE is set to 1
27
RX_DATA_AV_IRQ
R
0*, 1
Set to 1 by hardware, when the Buffer Manager holds
received data from reception to be written to RAM.
Note
: Only valid if the bit DIRECT_DATA_ACCESS_
ENABLE is set to 1
26
RX_BUFFER_OVERFLOW_I
RQ
R
0*, 1
Set to 1 by hardware, when the number of bytes received
exceeds the size of the RX buffer.
Note
: Reception is stopped in that case.
Note
: If RX_MULTIPLE is set to 1 this IRQ is raised when
the sum of all frames exceed the RX buffer size
25
TX_WATERLEVEL_IRQ
R
0*, 1
Set to 1 by hardware, when the number of bytes transmitted
is equal to the TX_WATERLEVEL
24
RX_WATERLEVEL_IRQ
R
0*, 1
Set to 1 by hardware, when the number of bytes received is
equal to the RX_WATERLEVEL

RX_SC_DET_IRQ
R
0*, 1
Set to 1 by hardware, when in reader mode a subcarrier is
detected
