Type Definitions

CECS_R

Field CECS reader - Clock error current status Note: CECS bit is valid only if the CED bit in the RNG_CR register is set to 0.

CEIS_R

Field CEIS reader - Clock error interrupt status This bit is set at the same time as CECS. It is cleared by writing 0. Writing 1 has no effect. An interrupt is pending if IE = 1 in the RNG_CR register.

CEIS_W

Field CEIS writer - Clock error interrupt status This bit is set at the same time as CECS. It is cleared by writing 0. Writing 1 has no effect. An interrupt is pending if IE = 1 in the RNG_CR register.

DRDY_R

Field DRDY reader - Data Ready Once the output buffer becomes empty (after reading the RNG_DR register), this bit returns to 0 until a new random value is generated. Note: The DRDY bit can rise when the peripheral is disabled (RNGEN=0 in the RNG_CR register). If IE=1 in the RNG_CR register, an interrupt is generated when DRDY=1.

SECS_R

Field SECS reader - Seed error current status One of the noise source has provided more than 64 consecutive bits at a constant value (“0” or “1”), or more than 32 consecutive occurrence of two bit patterns (“01” or “10”) Both noise sources have delivered more than 32 consecutive bits at a constant value (“0” or “1”), or more than 16 consecutive occurrence of two bit patterns (“01” or “10”)

SEIS_R

Field SEIS reader - Seed error interrupt status This bit is set at the same time as SECS. It is cleared by writing 0. Writing 1 has no effect. An interrupt is pending if IE = 1 in the RNG_CR register.

SEIS_W

Field SEIS writer - Seed error interrupt status This bit is set at the same time as SECS. It is cleared by writing 0. Writing 1 has no effect. An interrupt is pending if IE = 1 in the RNG_CR register.
