Table 13 lists the different values of the PLL1 multiplication factor.

PLL2 multiplication factors

The following enumeration defines the PLL2 multiplication factors. RCCU_PLL2_Mul

enumeration is declared in the file 71x_rccu.h:

typedef enum

{

RCCU_PLL2_Mul_12 = 0x01,

RCCU_PLL2_Mul_16 = 0x03,

RCCU_PLL2_Mul_20 = 0x00,

RCCU_PLL2_Mul_28 = 0x02

} RCCU_PLL2_Mul;

Table 14 lists the different values of the PLL2 multiplication factor.

PLL division factors

The following enumeration defines the PLL division factors. RCCU_PLL_Div enumeration is

declared in the file 71x_rccu.h:

typedef enum

{RCCU_Div_1 = 0x00,

RCCU_Div_2 = 0x01,

RCCU_Div_3 = 0x02,

RCCU_Div_4 = 0x03,

RCCU_Div_5 = 0x04,

RCCU_Div_6 = 0x05,

RCCU_Div_7 = 0x06

} RCCU_PLL_Div;
