CLOCK BLOCKING REGISTERS
The Receive Channel blocking Registers (RCBR1 /
RCBR2 / RCBR3 / RCBR4) and the Transmit Channel
Blocking Registers (TCBR1 / TCBR2 / TCBR3 / TCBR4)
control RCHBLK and TCHBLK pins respectively. (The
RCHBLK and TCHBLK pins are user programmable
outputs that can be forced either high or low during indi-
vidual channels). These outputs can be used to block
clocks to a USART or LAPD controller in ISDN–PRI
applications. When the appropriate bits are set to a one,
the RCHBLK and TCHBLK pin will be held high during
the entire corresponding channel time. See the timing in
Section 13 for an example. The TCBRs have alternate
mode of use. Via the CCR3.6 bit, the user has the option
to use the TCBRs to determine on a channel by channel
basis, which signaling bits are to be inserted via the
TSRs (the corresponding bit in the TCBRs=1) and
which are to be sourced from the TSER or TSIG pins
(the corresponding bit in the TCBR=0). See Section 7
for more details about this mode of operation.

NOTE:
If CCR3.6=1, then a zero in the TCBRs implies that signaling data is to be sourced from TSER (or TSIG if CCR3.2=1)
and a one implies that signaling data for that channel is to be sourced from the Transmit Signaling (TS) registers. See
definition below.
