Answer:
If the original value stored in the 16-bit register is overwritten with the value x75a2, it is not possible to recover the original value unless it was saved or backed up somewhere else.
Step-by-step explanation:
A 16-bit register can store 2^16 = 65536 distinct values, ranging from 0 to 65535 in decimal or 0x0000 to 0xFFFF in hexadecimal. Once a new value is written to the register, any previous value is lost and cannot be recovered unless a backup or copy of the original value was made before the write operation.
In this case, the original value stored in the register was overwritten with the value x75a2, which corresponds to the decimal value 30178. Therefore, the original value cannot be recovered from the register unless it was saved or backed up somewhere else before the write operation.
