D7 (MSB) specifies burst mode if set to 1. When
using burst mode, the address field of the com-
mand word must be "0000", any other value will
invalidate the command, and the CS62180B
will simply ignore it. This effectively
means that the command for a burst write is 80
(hex) and a burst read is 81 (hex).
Burst mode allows the sixteen registers to be
consecutively read or written. Writing all regis-
ters allows fast initialization at power-up or
system reset. (Note that the Receiver Status Reg-
ister, RSR, is read-only, so a write during burst
mode will have no effect.) When using burst
mode, registers are read or written in address or-
der, 0000 (RSR) to 1111 (RMR3). Burst mode
ends on the first rising edge of CS. See Table 1
for a complete list of the CS62180B
on-chip registers.

REGISTER NAME AND DESCRIPTION
(R) RECEIVE
0000
RSR
Receive Status Register - A read only register which reports all active receiver
alarm conditions.
R
0001
RIMR
Receive Interrupt Mask Register - A mask which allows selection of individual
alarm conditions for generation of hardware interrupt.
R
0010
BVCR
Bipolar Violation Count Register - A bipolar violation alarm is generated after
this 8 bit counter surpasses it’s user definable limit.
R
0011
ECR
Error Count Register - Two separate 4 bit counters, which record OOF errors,
and frame bit or CRC errors. Like BVCR, each can be preset to a saturation
point.
R
0100
CCR
Common Control Register - Selects global configuration options, such as:
framing mode, zero suppression, or loopback.
T/R
0101
RCR
Receive Control Register - Selects receiver specific options, such as the resync
algorithm or insertion of digital milliwatt codes.
R
0110
TCR
Transmit Control Register - Selects transmitter specific options, such as alarm
generation, clear or idle channel enable, and external S-bit or CRC insertion.
T
0111
1000
1001
TIR1
TIR2
TIR3
Transmit Idle Registers - Each bit of the three TIR registers corresponds to an
individual DS0 channel. When set, that channel is replaced with an idle code.
T
1010
1011
1100
TTR1
TTR2
TTR3
Transmit Transparent Registers - Each bit corresponds to a DS0 channel. When
set, that signaling and B7 zero suppression is disabled for that channel.
T
1101
1110
1111
RMR1
RMR2
RMR3
Receive Mark Registers - Each bit corresponds to a DS0 channel. When set, the
channel data is replaced with an idle or digital milliwatt code.
