PARITY : Parity Error. Set by serial parity mismatch on incoming data
byte.
FRAME : Framing Error. Set when an incoming serial data byte is missing
the STOP bit.
NOISE : Noise Error. Set when an incoming serial data byte does not
present a steady logic level during each asynchronous bit-
period window.
HWOVRN : Hardware Overrun. Set when an incoming serial data byte is
lost due to internal processor latency. Causes the Input Buffer
to be flushed, and resets the command parser.
OVR : Input Buffer Overrun. Set when the Input Buffer is overrun
by incoming data. Causes the Input Buffer to be flushed, and
resets the command parser.
RTSH : Undefined for the SIM984.
CTSH : Undefined for the SIM984.
DCAS : Device Clear. Indicates the SIM984 received the Device Clear
signal (an RS-232 break ). Clears the Input Buffer and Output
Queue, and resets the command parser.
The CESE acts as a bitwise AND with the CESR register to produce
the single bit CESB message in the Status Byte Register (SB). It can
be set and queried with the CESE(?) command.
This register is cleared at power-on.
