Jump to Reset Request (2Ch; D203h)
The Jump to Reset Request command requests the tag perform a hard reset. The reset
will occur the same as a hardware reset and the decision is made by the tag to perform a
cold boot or a warm boot by analyzing the first 32 bits of page 0000 in the tag. If the bits
are all 0s or all 1s, then a cold boot will be performed, otherwise a warm boot will occur.
