FREQUENCY GENERATOR
A versatile frequency generator section is provided (see
Fig.3). For normal operation, use a 3.58 MHz quartz
crystal or PXE resonator. The frequency generator
includes precision circuitry for dual tone multifrequency
(DTMF) signals, which is typically used for tone dialling
telephone sets.
The TONE output can alternatively issue twelve modem
frequencies for data rates between 300 and 1200 bits/s.
In addition to DTMF and modem frequencies, two octaves
of musical scale in steps of semitones are available.

Frequency generator derivative registers
Table 2 gives the derivative addresses, mnemonics and access types of the frequency generator derivative registers.
The addresses 03H to FFH are not used.
