RDY=Busy
Data. The content of this register is valid only when RNG_IS = 1. When TRNG is disabled, read returns 0x0000 0000.
| RDY | 32-bit random data is ready to read from TRNG_DATA register. Reading TRNG_DATA when RND_RDY=0 will return all 0’s. IRQ is generated when RND_RDY=1 if TRNG_CN.RND_IRQ_EN=1. 0 (Busy): TRNG Busy 1 (Ready): 32 bit random data is ready |
