7.6.2 Multiple Power-Up Default Conditions

There are two additional devices under the TCAL6416R which have different register start-up values. This is done to assist systems with different power-up requirements and accommodate their initialization software. Table 7-4 lists the names of the devices and changes in their start-up values. TCAL6416RADTOR (referenced as TCAL6416RA on Section 7.6.3 and Section 7.64) has updated power-up values for Output Port and Configuration registers. TCAL6416RBDTOR (referenced as TCAL6416RB on Section 7.6.3 and Section 7.64) has updated power-up values for Polarity Inversion, Pull-Up/Pull-Down Enable and Interrupt Mask registers.
