Figure 3. Offset Register Formats and Default Values for the A and B FIFOs
contains four 8-bit offset registers which can be loaded with data on the inputs,
or read on the outputs. See Figure 3 for details of the size of the registers and
the default values.
If FIFO A (B) is configured to have programmable flags, when the
WENA1
(
WENB1) and WENA2/LDA(WENB2/LDB) are set LOW, data on the DA (DB)
inputsarewrittenintotheEmpty(LeastSignificantBit)Offsetregisteronthefirst
LOW-to-HIGH transition of the WCLKA (WCLKB). Data are written into the
Empty (Most Significant Bit) Offset register on the second LOW-to-HIGH
transitionofWCLKA(WCLKB),intotheFull(LeastSignificantBit)Offsetregister
on the third transition, and into the Full (Most Significant Bit) Offset register on
thefourthtransition. ThefifthtransitionofWCLKA(WCLKB)againwritestothe

However,writingalloffsetregistersdoesnothavetooccuratonetime. One
or two offset registers can be written and then by bringing
LDA(LDB) HIGH,
FIFO A (B) is returned to normal read/write operation. When
LDA(LDB) is set
LOW, and
WENA1 (WENB1) is LOW, the next offset register in sequence is
written.

transition of the Read Clock RCLKA (RCLKB).
A read and write should not be performed simultaneously to the offset
registers.
