3 TSB12LV26 Controller Programming Model

This section describes the internal registers used to program the TSB12LV26. All registers are detailed in the same format: a brief description for each register, followed by the register offset and a bit table describing the reset state for each register.

A bit description table, typically included when the register contains bits of more than one type or purpose, indicates bit field names, field access tags which appear in the type column,and a detailed field description. Table 3±1 describes the field access tags.
