T7121 HDLC Interface for ISDN (HIFI-64)
Functional Description
(continued)
Note: A special block-move mode allows data to be loaded as a block to the FIFO. A block move is accomplished only in the MUXed address
and data mode by setting the BM bit in register 0 (R0—B3) to 1 and holding AD6 high during the address cycle of the ALE. All writes then
go directly to the transmit FIFO and all reads address the receive FIFO. Normal ALE mode addressing is accomplished by holding AD6
low during the ALE address cycle. Block move is enabled and disabled by the BM bit in register 0 (R0—B3).

Transmit Queue Status.
Read only. Bits 0—6 indicate how
many bytes can be added to the transmit FIFO. The bits are
encoded in binary, with bit 0 being the LSB.
Transmitter Empty Dynamic.
Read only. When this bit is
high, it indicates that the number of empty locations available
in the transmit FIFO is greater than or equal to the value pro-
grammed in the TIL bits (see register 1). This bit is cleared only
when the transmit FIFO is loaded above the preprogrammed
empty-trigger level.

The user data bytes to be transmitted are loaded through this register
(write). Also, the user data bytes received are accessed through this
register (read).
