RNG status register
DRDY | Data ready Note: If IE=1 in RNG_CR, an interrupt is generated when DRDY=1. It can rise when the peripheral is disabled. When the output buffer becomes empty (after reading RNG_DR), this bit returns to 0 until a new random value is generated. |
CECS | Clock error current status Note: This bit is meaningless if CED (Clock error detection) bit in RNG_CR is equal to 1. |
SECS | Seed error current status ** More than 64 consecutive bits at the same value (0 or 1) ** More than 32 consecutive alternances of 0 and 1 (0101010101…01) |
CEIS | Clock error interrupt status This bit is set at the same time as CECS. It is cleared by writing it to 0. An interrupt is pending if IE = 1 in the RNG_CR register. Note: This bit is meaningless if CED (Clock error detection) bit in RNG_CR is equal to 1. |
SEIS | Seed error interrupt status This bit is set at the same time as SECS. It is cleared by writing it to 0. ** More than 64 consecutive bits at the same value (0 or 1) ** More than 32 consecutive alternances of 0 and 1 (0101010101…01) An interrupt is pending if IE = 1 in the RNG_CR register. |
