• Manufacturer Part Number: w925e625
• Description: 8-bit Cid Microcontroller
• Manufacturer: ETC-unknow

Notes:
1. SIN227 specifies that the AC and DC loads should be applied at 20
2. SIN227 specifies that the AC and DC loads should be removed between 50 – 150Ms after the end of the FSK signal.
3.
The FSKE bit should be set low to disable the FSK decoder when FSK is not expected. The tone alerting signal speech
and the DTMF tones are in the same frequency band as the FSK signal.
