Description
Reserved. These bits are implemented but reserved for future use. When writing to this
MSR, software should set these bits to 0 and ignore them on read.
TRNG Test Mode. This bits enables the TRNG test mode. Deterministic TRNG values
are generated when this bit is 1.
TRNG Noise Enable. This bit enables the noise generator for the TRNG.
0: Disable.
1: Enable.
TRNG SEL. These bits select post processing of the TRNG output.
00: Raw output.
01: LFSR output.
10: Whitener output.
11: LFSR + Whitener output.
Reserved. These bits are implemented but reserved for future use. When writing to this
MSR, software should set these bits to 0 and ignore them on read.
Time Write. This bit controls the EEPROM write timing within the EEPROM interface
module. Normally the EEPROM interface signals completion immediately after it finishes
shifting out the last bit of a write operation. The start of any other EEPROM access
begins a polling process. Once, the EEPROM has completed its internally timed write
operation, it responds to the polling and the next operation can begin. Setting this bit
causes the EEPROM interface to delay for slightly more than 10 ms after writing to the
EEPROM, before indicating write completion. That is, the start bit will be held high, and
the interrupt and SMI generation will be delayed for 10 ms. This ensures that the
EEPROM has completed its internal write and should be ready to respond to the next
access immediately. This is a “chicken” bit to avoid using the acknowledge polling (as
described in the Atmel datasheet), after a write.
