I'm using evm6678l board , I read the "evmc66x_i2c.c" and "evmc66x_i2c.h" ,
In evmc66x_i2c.h:
"// I2C prescalar set to 16 to get module freq (1000MHz/6)/17 = 9.8 MHz"
"#define I2C_PRESCALER (16)"
It calculate the module clock using "module freq (1000MHz/6)/17 = 9.8 MHz" , I think the 1000MHZ is the system clock of the 6678DSP, But where is the "/6" comes from?
If it is the value of PLL1 divider, which header file does this "6" exist in? or In which header file does the PLL1 set exist in?
Thank you
