W83195WG-382/W83195CG-382
STEPLESS FOR ATI K8 CLOCK GENERATOR
8. ACCESS INTERFACE
The W83195BR-382 provides I2C Serial Bus for microprocessor to read/write internal registers. In the
W83195BR-382 is provided Block Read/Block Write and Byte-Data Read/Write protocol. The I2C
address is defined at 0xD2.
The register number is increased by one if using byte data read/write protocol.
Example: In block mode, byte number of program register is 1
In byte mode, byte number of program register is 2 (Byte number of block mode +1)
8.1 Block Write protocol
8.2 Block Read protocol
## In block mode, the command code must filled 8’h00
8.3 Byte Write protocol
8.4 Byte Read protocol
