CLOCK BLOCKING REGISTERS
The Receive Channel Blocking Registers (RCBR1/RCBR2/RCBR3) and the Transmit Channel Blocking
Registers (TCBR1/TCBR2/TCBR3) control the RCHBLK and TCHBLK pins respectively.
The
RCHBLK and TCHBLK pins are user programmable outputs that can be forced either high or low during
individual channels. These outputs can be used to block clocks to a UART or LAPD controller in
Fractional T1 or ISDN–PRI applications. When the appropriate bits are set to a 1, the RCHBLK and
TCHBLK pins will be held high during the entire corresponding channel time.
See the timing in
Section 21 for an example.
