Section 20 Sound Generator (SDG)
20.4.2
The SDG provides tone frequency output in the range of 31 Hz to 20 kHz, with precision of 1% or
less.
The tone frequency is calculated by:
Setting values of the TONE bit in SGTFR and SFS bit in SGFSR are calculated by:
An example of relationship between the tone frequency and output error is shown in table 20.3.
Table 20.3 Relationship between Tone Frequency and Output Error
Note: SGCLK = 5 MHz
Since changing Pφ frequency affects the tone frequency, care should be taken when changing it.

Reference frequency (Hz) = SGCLK (Hz)/SFS
Tone frequency (Hz) = Reference frequency (Hz)/(2 × TONE)
= SGCLK (Hz)/(2 × SFS × TONE)
SFS = SGCLK (Hz)/reference frequency (Hz) (0 < SFS ≤ 255)
TONE = Reference frequency (Hz)/(2 × TONE frequency (Hz)) (0 < TONE ≤ 127)
