TRNGEN : Random Number Generator Enable Bit\nThis bit can be set to 1 only after ACT (TRNG_ACT[7]) bit was set to 1 and READY (TRNG_CTL[7]) bit became to 1.\nNote: TRNGEN is an enable bit of digital part. When TRNG is not required to generate random number, TRNGEN bit and ACT (TRNG_ACT[7]) bit should be set to 0 to reduce power consumption.
bits : 0 - 0 (1 bit)
access : read-write
Enumeration:
#0 : 0
TRNG Disabled
#1 : 1
TRNG Enabled
End of enumeration elements list.
DVIF : Data Valid (Read Only)\nThis bit is cleared to '0' by read TRNG_DATA.
bits : 1 - 1 (1 bit)
access : read-only
Enumeration:
#0 : 0
Data is not valid. Reading from RNGD returns 0x00000000
#1 : 1
Data is valid. A valid random number can be read form RNGD
End of enumeration elements list.
CLKPSC : Clock Prescaler\nThe CLKP is the peripheral clock frequency range for the selected value , the CLKP must higher than or equal to the actual peripheral clock frequency (for correct random bit generation). To change the CLKP contents, first set TRNGEN bit to 0 and then change CLKP; finally, set TRNGEN bit to 1 to re-enable the TRNG module.

READY : Random Number Generator Ready (Read Only)\nAfter ACT (TRNG_ACT[7]) bit is set, the READY bit become to 1 after a delay of 90us~120us.
bits : 7 - 7 (1 bit)
access : read-only
Enumeration:
#0 : 0
RNG is not ready or was not activated
#1 : 1
RNG is ready to be enabled.
End of enumeration elements list.
SEEDGEN : Random Number Seed Generator Enable Bit [for TRNG+PRNG]\nThis bit can be set to 1 only after ACT (TRNG_ACT[7]) bit was set to 1 and READY (TRNG_CTL[7]) bit became to 1.\nNote: If users want to execute TRNG+PRNG mode, they should set SEEDGEN to 1. When SEEDGEN was set to 1, users can't read the data from TRNG Data Register.
bits : 8 - 8 (1 bit)
access : read-write
Enumeration:
#0 : 0
Seed generator disabled
#1 : 1
Seed generator enabled
End of enumeration elements list.
SEEDRDY : Random Number Seed Ready (Read Only) [for TRNG+PRNG]\nNote 1:This bit is cleared to '0' when SEEDGEN is 1.\nNote 2: If SEEDRDY become to 1, then SEEDGEN will be cleared to 0.
bits : 9 - 9 (1 bit)
access : read-only
Enumeration:
#0 : 0
Seed is not ready or was not activated

Seed is ready for PRNG

ACT : Random Number Generator Activation\nAfter enabling the ACT bit, it will active the TRNG module and wait the READY (TRNG_CTL[7]) bit to become 1.\nNote: ACT is an enable bit of analog part. When TRNG is not required to generate random number, TRNGEN (TRNG_CTL[0]) bit and ACT bit should be set to 0 to reduce power consumption.
bits : 7 - 7 (1 bit)
access : read-write
Enumeration:
#0 : 0
TRNG inactive
#1 : 1
TRNG active
