Prime function
The basic function of YM2610 can be divided roughly into four sound source part of FM sound source, SSG
sound source, and ADPCM sound source.
1) FM sound source part
The basic function of the FM sound source part is the same as OPN(YM2203).
Pronunciation mode
Four operator FM method and six sound pronunciation simultaneously.
Algorithm
Eight kinds.
Parameter
The register address and refer to the FM sound source part.
LFO function
Sine wave LFO. Pitch (PM) and, it modulates amplitude (AM). The LFO
frequency is changeable. AM on/off is possible of PMS, the AMS control, and each operator.
Compound sine wave synthesis One sound is possible in six sounds. Timer function Two kinds of timers
of A and B.
Output control
On/off of L and R.
2) SSG sound source part
The SSG sound source part is the same as OPN excluding the output method.
Pronunciation form
Three rectangular liquid sounds + white noise.
Function of each data
Refer to the register address.
Output
It outputs it from one terminal by internal mixing.
I/O port
Eight bit general purpose I/O port x2
3) ADPCM sound source part
Speech analysis, synthesis, and external memory control of ADPCM sound source part. It is composed of the
AD/DA conversion function.
Sampling rate
18.5 kHz , 1.8kHz-55.5kHz
AD/DA conversion
8-bit
ADPCM analysis
4-bit
Linear interpolation rate
55.5kHz
Data memory
Memory that external RAM-ROM
Output control
On/off of L and R.
No sound discrimination
The state under the analysis of a no sound can be identified.
4) DAC
Exclusive use DAC YM3016 is used.
