• Description: Mpc823 Powerquicc Integrated Communications Processor For Portable Systems
• Manufacturer: Freescale Semiconductor, Inc

A bit is cleared by writing a 1 (writing a zero has no effect) and more than one bit can be
cleared at a time. All unmasked bits must be cleared before the communication processor
module clears the internal interrupt request. This register is cleared at reset and can be read
at any time.
Bits 0–2, 5, and 11—Reserved
These bits are reserved and must be set to 0.
GLR—Glitch on RX
If set, this bit indicates that a serial communication controller has encountered a clock glitch
on the receive clock.
GLR—Glitch on TX
If set, this bit indicates that a serial communication controller has encountered a clock glitch
on the transmit clock.
AB—Auto Baud
If set, this bit indicates that an auto baud lock has been detected. The core must rewrite the
baud rate generator with the precise divider value for the preferred baud rate. Refer to
Section 16.8.2 Baud Rate Generator Configuration Registers for more details.
IDL—Idle Sequence Status Changed
If set, this bit indicates that a change in the serial line’s status has been encountered on the
UART channel. The real-time status of the line can be read in the SCCS–UART. Idle is
entered when a character of all ones is received and it is exited when a single zero is
received.
GRA—Graceful Stop Complete
If set, this bit indicates that a graceful stop, which is initiated by the GRACEFUL STOP
TRANSMIT command, is complete. This bit is set as soon as the transmitter has finished
with any buffer in progress when the command was issued. It is set immediately if no buffer
is in progress when the command is issued.
BRKE—Break End
If set, this bit indicates that an end-of-break sequence has been found. This indication is set
no sooner than after an idle bit is received following a break sequence.
