4. Indirect Registers
Indirect registers are not directly mapped into memory
but are accessible through the IDA and IAA registers. A
write to IDA followed by a write to IAA is interpreted as a
write request to an indirect register. In this case, the
contents of IDA are written to indirect memory at the
location referenced by IAA at the next indirect register
update. A write to IAA without first writing to IDA is
interpreted as a read request from an indirect register.
In this case, the value located at IAA is written to IDA at
the next indirect register update. Indirect registers are
updated at a rate of 16 kHz. For pending indirect
register transfers, IAS (direct Register 31) will be one
until
(Register 20), can be generated upon completion of the
indirect transfer.
4.1. DTMF Decoding
All values are represented in 2s-complement format.
Note: The values of all indirect registers are undefined follow-
