Frequency Modulation Resister Setting (Write Operation)
Write Operation
Frequency modulation is set by serial input resister. Serial input resister is controlled by serial input clock (SCLK),
serial input enable (SENABLE) and serial input data (SDATAIN).
When SENABLE is "L" level, SDATAIN is written to serial input resister by SCLK. SDATAIN is composed by 4 bit
address + 3 bit W/R distinction data + 16 bit resister data.
After SENABLE change to "H", more than 20 dummy SLCK cycle is needed.
tDS
4bit address
tDH
20 cycles dummy input
tDS
16bit data
For write operation, set to "H" 3 cycles continuously.
