DESCRIPTION/FUNCTION
BVCR2
0000
Bipolar Violation Count Register 2. LSW of a 16-bit presettable counter that
records individual bipolar violations.
BVCR1
0001
Bipolar Violation Count Register 1. MSW of a 16-bit presettable counter that
records individual bipolar violations.
CRCCR
0010
CRC Error Count Register. 8-bit presettable counter that records CRC6 errored
words in the 193E frame mode.
OOFCR
0011
OOF Count Register. 8-bit presettable counter that records OOF events. OOF
events are defined by RCR1.5 and RCR1.6.
FECR
0100
Frame Error Count Register. 8-bit presettable counter that records individual
bit errors in the framing pattern.
RSR1
0101
Receive Status Register 1. Reports alarm conditions.
RIMR1
0110
Receive Interrupt Mask Register 1. Allows masking of individual alarm-
generated interrupts from RSR1.
RSR2
0111
Receive Status Register 2. Reports alarm conditions.
RIMR2
1000
Receive Interrupt Mask Register 2. Allows masking of individual alarm-
generated interrupts from RSR2.
RCR1
1001
Receive Control Register 1. Programs device operating characteristics.
RCR2
1010
Receive Control Register 2. Programs device operating characteristics.
SERIAL PORT INTERFACE
The port pins of the DS2182A serve as a microprocessor/ microcontroller-compatible serial port. Eleven
on-board registers allow the user to update operational characteristics and monitor device status via a host
controller, minimizing hardware interfaces. The port on the DS2182A can be read from or written to at
any time. Serial port reads and writes are independent of T1 line timing signals RCLK, RPOS, and
RNEG. However, RCLK is needed in order to clear RSR1 and RSR2 after reads.
ADDRESS/COMMAND
Reading or writing the control, configuration or status registers requires writing one address/command
byte prior to transferring register data. The first bit written (LSB) of the address/command word specifies
