is in the system. The Fuse Parity Error Bit is also included in
this register. The bit encoding is shown in
FPAR – Fuse Parity Error Bit
Since these parameters can be impacted by the state of the
fuses, a fuse parity is calculated and stored during device
manufacturing. When the device is powered up, the current
fuse parity is checked against the stored parity. If they do not
match this bit is set. This bit is also set if the part is
untrimmed.

• 0 = No fuse parity error.
• 1 = There is a fuse parity error.
Some parameters in the device are trimmed by fuses.
