Table 5-44 describes the PLL SSMOD control bitfields. Figure 5-21 describes the connection between a SSMOD and a PLL.
Parameter | Register | Description |
---|---|---|
SSMOD enable control | <PLL_name>n_SS_CTRL[31] BYPASS_EN (For example, MCU_PLL0 - MCU_PLL0_SS_CTRL[31] BYPASS_EN) | Enable/disable the PLL SSMOD feature. |
Type of spread | <PLL_name>n_SS_CTRL[4] DOWNSPREAD_EN (For example, MCU_PLL0 - MCU_PLL0_SS_CTRL[4] DOWNSPREAD_EN) | Selects center spread or down spread clock variance |
Modulation dvider | <PLL_name>n_SS_SPREAD[19-16] MOD_DIV (For example, MCU_PLL0 - MCU_PLL0_SS_SPREAD[19-16] MOD_DIV) | Input clock divider. This divider sets the modulation frequency. |
Spread Depth | <PLL_name>n_SS_SPREAD[4-0] SPREAD (For example, MCU_PLL0 - MCU_PLL0_SS_SPREAD[4-0] SPREAD) | Sets the spread modulation depth. |
