W 0, 1
ENABLE flag
W 0, 1 Writing 1 to this register does set the corresponding IRQ
ENABLE flag
Access Value Description
R 0 Reserved
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.
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
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
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
R 0*, 1 Set to 1 by hardware, when the number of bytes transmitted
is equal to the TX_WATERLEVEL
R 0*, 1 Set to 1 by hardware, when the number of bytes received is
equal to the RX_WATERLEVEL
R 0 Reserved
R 0*, 1 Set to 1 by hardware, when in reader mode a subcarrier is
detected
