6.6.2 State Registers
The QMC has two sets of state parameters—global and channel-specific. These registers
change if the QMC is running and the SCC is receiving clock.
Channel-specific
parameters—
HDLC and
transparent
Global state
parameter
Channel-specific
parameters—
HDLC
Channel-specific
parameters—

Holds pointer to current data in buffer.
Holds down-counter of data left to transmit in this buffer
descriptor—loaded when the buffer descriptor is
opened with the BD length field.
Holds pointer to address inside the current buffer
where data will be received.
Holds down-counter of space left in this Rx buffer—
loaded when the BD is opened with the MRBLR field.
bit 0
• 1 if the QMC is stopped or has not started
• 0 if the QMC is running
bit 8— currently transmitting a frame
bit 9— buffer descriptor is currently open (data is being
transmitted from a BD)
bit 12— channel has been initialized and is running
bit 8—currently receiving a frame
bit 9— buffer descriptor is currently open (data is being
received into a BD)
bit 11— reception is halted
low word—current BD status word
