Description

RCC PLL secure configuration register1

Fields

PLL1SEC	Defines the secure protection of the PLL1 PLL configuration bits. 0 (B_0x0): PLL1 configuration bits are accessible by non-secure software only (default after reset) 1 (B_0x1): PLL1 configuration bits are accessible by secure software only
PLL2SEC	Defines the secure protection of the PLL2 PLL configuration bits. 0 (B_0x0): PLL2 configuration bits are accessible by non-secure software only (default after reset) 1 (B_0x1): PLL2 configuration bits are accessible by secure software only
PLL3SEC	Defines the secure protection of the PLL3 PLL configuration bits. 0 (B_0x0): PLL3 configuration bits are accessible by non-secure software only (default after reset) 1 (B_0x1): PLL3 configuration bits are accessible by secure software only
PLL4SEC	Defines the secure protection of the PLL4 PLL configuration bits. 0 (B_0x0): PLL4 configuration bits are accessible by non-secure software only (default after reset) 1 (B_0x1): PLL4 configuration bits are accessible by secure software only
