Data Sheet

Zarlink Semiconductor Inc.
ADDRESSES 1Fh to 3Fh are RESERVED
Note: Bits marked "-" are reserved bits and should be written with logic "0".
The frequency of the high group tone is programmed by writing an 8-bit hexadecimal coefficient at this address according to the
following equation:
Frequency (in Hz) = 7.8125 x COEFF
Where the hexadecimal COEFF is converted into a decimal integer between 0 and 255. Frequency resolution is 7.8125Hz in the range
0 to 1992 Hz.

When high, the anti-howling circuit is enabled. When low, the anti-howling circuit is disabled.
Encode the operational mode of the anti-howling circuit as follows. Details of each mode are found in the functional
description of the anti-howling circuit.

THh6-0
Seven bits encoding the magnitude of the high threshold level. Encoding is in PCM sign-magnitude excluding the sign bit.
THh0 - THh3 encode the step number while THh4 - THh6 encode the chord number. The default setting of 'X011 0000'
encodes chord 3 step 0. The difference between the high and low thresholds defines the hysteresis for anti-howling.
