Name:
Cfo_TXRXinfoFlags01
Cfo_TXRXinfoFlags02
This register can be used to specify that the number of unprocessed elements in the transmit and receive buffers is
indicated in the upper 4 bits of the "TX0[x]CountReadBack" and "RX0[x]Count" registers for the respective interface.
Data type Value
USINT See bit structure.
Bit structure:
Bit Description Value Information
0 The "TX0[x]Count" is read in the "TX0[x]CountReadBack" on
page 1673 register.
0 TxFifoInfo
"Mode of channel TX0[x]CountReadBack" in the AS I/O config-
uration
1 The "TX0[x]Count" is read in the "TX0[x]CountReadBack" on
page 1673 register.
The upper 4 bits are used to return the number of frames in the
transmit buffer that have not been transmitted.
0 The number of received telegrams is shown in the
"RX0[x]Count" on page 1673 register.
1 RxFifoInfo
"Mode of channel RX0[x]Count" in the AS I/O configuration
1 The number of received telegrams is shown in the lower 4 bits
of the "RX0[x]Count" on page 1673 register.
The upper 4 bits are used to indicate the number of received but
not acknowledged telegrams in the receive buffer.
