Capability register (read-only)
This 16-bit register is read-only, and provides the TS capabilities which comply with the
minimum JEDEC TSE2002a2 specifications (see Table 6 and Table 7 on page 18). The
STTS2002 resolution is programmable via writing to pointer 08 register. The power-on
default value is 0.25 °C/LSB (10-bit).
