HRA Status 1 (HS1)
The register is configured as follows:
Read Address is: 55
H
Reset Value is: 00
H
Bit
Name
Description
7
RXCHNL
Receive Channel Latched (RXCHNL)
. When this bit is high it indicates that a new
receive channel number has been latched internally, and is as shown in the currently
read byte. A system read of HRA Status register 3 will automatically clear this status
bit. In dedicated receive mode, this bit will be held high. On reset, this bit will be low.
6
RXACT
Receiver Active (RXACT)
. When high, this status bit indicates that the receiver is
currently active. On reset, this bit will be low, and RxCEN will be disabled. In
dedicated receive mode, this bit will be held high.
5
CTSACT
Clear-to-Send Active (CTSACT)
. If high, this status bit indicates that the receiver is
currently transmitting a clear-to-send go-ahead pattern to the peripheral on the
transmit channel denoted by PRXi. In dedicated receive mode, this bit will be held
low, disabling CTS generation and transmission. On reset, this bit will be low.
4
FLAG
Flag Detect (FLAG)
. When high, FLAG indicates that the Auto-hunt circuitry has
detected a request-to-send from a peripheral, but has not yet acted upon it. FLAG
will also go high if the system injects an SFLAG via the micro interface. As soon as
the RX circuitry selects the corresponding peripheral for system receive, this status
bit is cleared. On reset, this bit will be low. This bit is primarily used for test purposes.
3-0
PRX4-1
Present Receive Channel (PRX)
. The current receive channel number is contained
in these five bits. Reading the channel number via HRA Status register 3 clears the
status bit RXCHNL. PRX4-1 represent channels 0-15 on STi1 stream, with HC1
register bit CD=0, or channels 16 to 31 with bit CD=1. On reset, channel 0 will be
selected, but will be inactive.
