3.3 Interrupt Mask Register, RNG_IMR

The RNG_IMR register enables you to mask certain conditions and prevent the assertion of the interrupt output.

The following table lists the RNG_IMR bit assignments.

Table 3-3 RNG_IMR

Bits Name Description
[31:4] - Reserved.
[3] VN_ERR_INT_MASK Set to 1 to mask the Von Neumann error, and prevent the TRNG from setting the cc_host_int_req interrupt HIGH for Von Neumann errors.
[2] CRNGT_ERR_INT_MASK Set to 1 to mask the CRNGT error, and prevent the TRNG from setting the cc_host_int_req interrupt HIGH for CRNGT errors.
[1] AUTOCORR_ERR_INT_MASK Set to 1 to mask the Autocorrelation error, and prevent the TRNG from setting the cc_host_int_req interrupt HIGH for Autocorrelation errors.
[0] EHR_VALID_INT_MASK Set to 1 to mask when the TRNG has collected 192 bits, and prevent the TRNG from setting the cc_host_int_req interrupt HIGH when 192 bits are collected.
