FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
is in the system. The Fuse Parity Error Bit is also included in
this register. The bit encoding is shown in Figure 35
Figure 35. Mask ID Register Bit Assignments
FPAR – Fuse Parity Error Bit
0 = No fuse parity error.
1 = There is a fuse parity error.
Some parameters in the device are trimmed by fuses.
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.
ID[6:0] – Mask ID number
The mask ID that identifies different versions or revisions
of the device.
Check Pattern and Negative Check Pattern
RegisteRS
These read-only registers are for checking whether there
is a stuck bus bit. These registers are read as a 3 byte burst
using a standard SPI burst frame The bit encoding is shown
