10 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 TCHCLK 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 USART or LAPD controller in
Fractional T1 or ISDN-PRI applications. When the appropriate bits are set to a 1, the RCHBLK and
TCHCLK pins will be held high during the entire corresponding channel time. See the timing diagrams in
Section 14 for an example.
