ZHCSAV1A April 2013 – September 2019 TMP108
PRODUCTION DATA.
Figure 11 shows the internal register structure of the TMP108. Use the 8-bit pointer register to address a given data register. The pointer register uses the two LSBs (see Table 12) to identify which of the data registers respond to a read or write command. Table 3 identifies the bits of the pointer register byte. Table 4 describes the pointer address of the registers available in the TMP108. The power-up reset value of the P1 and P0 bits is 00.
Figure 11. Internal Register Structure | P7 | P6 | P5 | P4 | P3 | P2 | P1 | P0 |
|---|---|---|---|---|---|---|---|
| 0 | 0 | 0 | 0 | 0 | 0 | Register Bits | |
| P1 | P0 | REGISTER |
|---|---|---|
| 0 | 0 | Temperature register (read only, default) |
| 0 | 1 | Configuration register (read/write) |
| 1 | 0 | TLOW register (read/write) |
| 1 | 1 | THIGH register (read/write) |
