Device Communication Modes

The TPIC83000 is a pressure sensing conditioning device that interfaces with a microprocessor. The TPIC83000

has register addressing that is partitioned into seven bank mode addresses (labeled 00h to 06h) and 27 field

mode addresses (labeled 00h to 1Ah) as shown in Table 3 and Table 4. Bank addresses 00h to 05h are located

in the EEPROM, and bank address 06h is located in the logic (DSP) block. Field addresses 00h to 16h are

located in the EEPROM, and field addresses 17h to 1Ah are located in the logic (DSP) block. See Table 3 and

Table 4 for details.
