HIB Clock Generator
|
HIB CLOCK GENERATOR | ||||
|
|||||
|
|
|
|
|
|
The HIB contains a CLOCK generator controlled by the system register 0x80C. | |||||
The register 0x80c handle two parameters: | |||||
|
- mask 0x000F: the divisor for the HIB logic, | ||||
|
- mask 0X03F0: the clock frequency. | ||||
