TS1482 rev. 2
The PROM contains calibration data and the identification code (ID). It is read at power-on reset, when its
contents are copied to the shadow register. The PROM contains one parity bit. If a parity error occurs during
reading of the PROM, the product will enter the PROM Reload state, as described below.
In this state, the product will read the PROM contents again with 1 s intervals until a successful read is completed.
The PROM reading can fail for two reasons:
If command via SPI is activated while the product is in the PROM reload/reset state, the FSI will be set.
After copying the PROM contents to the shadow register, a 16 bit CRC is calculated using the CCITT polynomial.
This checksum is stored with the data, and is verified for each measurement cycle. If an error is detected, the
product will return a single byte with an error code, and then enter PROM Reload / Reset state.
A supply voltage below 2.1 V (nominal) has two consequences:
The product uses a separate circuit with an output signal called VMIN, to detect this condition. VMIN = 1 will occur
if VDD<2.1 ±0.1V.
If low supply voltage causes the information in the shadow register to be corrupted, the product will enter PROM
reload state as described in section 10.2.
If high temperature causes the information in the shadow register to be corrupted, the SP100-15 will enter PROM
reload state as described in section 10.2.
The overflow bit will be set by an over- or underflow in the ADC or compensation module. For temperature and
supply measurements, ADC overflow will not saturate the compensated output value.
- Parity error in PROM data
- Reading not allowed due to supply voltage below minimum for read operation
- Reading of the PROM is not allowed
- The measurement accuracy cannot be guaranteed
