Unused. Read all 0’s.
Write a 1 to increment the recombiner delay of IMA Group #7. The bit will return to 0 when
the delay is adjusted. Writing a 0 has no effect.

Write a 1 to increment the recombiner delay of IMA Group #2. The bit will return to 0 when
the delay is adjusted. Writing a 0 has no effect.
Write a 1 to increment the recombiner delay of IMA Group #1. The bit will return to 0 when
the delay is adjusted. Writing a 0 has no effect.
Write a 1 to increment the recombiner delay of IMA Group #0. The bit will return to 0 when
the delay is adjusted. Writing a 0 has no effect.
Unused. Read all 0’s.
Upon a write to this register, the bit will go to 0 and will return to 1 when the transfer is
completed
Toggle Bit. Changes its state after each rising edge of the bit 7 (ready bit).
Write 0 to initiate a transfer from the MT90222/3/4 registers to the external RAM.
Write 1 to initiate a transfer from the external RAM to the MT90222/3/4 registers.
Unused. Read all 0’s
Reserved. Write 0 for normal operation.
When bit 1 is 1, there is no access to the external RAM (no reset or read or write action
done).
When bit 1 is 0 and bit 0 is 0, then the external RAM is initialized.
When bit 1 is 0 and bit 0 is 1, then a read or write access to the external RAM is
performed, as defined by bit 5.
0x0281
Used to increment the recombiner delay for an IMA Group. For MT90222 only
groups 0,1,2 and 3 are used.
The value is in the Guardband/Delta Delay register
