17 / 41 page  LM63 www.ti.com SNAS190E – SEPTEMBER 2002 – REVISED MAY 2013 LM63 REGISTERS This section includes the following subsections: REGISTER MAP IN HEXADECIMAL ORDER, which shows a summary of all registers and their bit assignments; REGISTER MAP IN FUNCTIONAL ORDER; and REGISTER DESCRIPTIONS IN FUNCTIONAL ORDER, which provides a detailed explanation of each register. Do not address the unused or manufacturer’s test registers. REGISTER MAP IN HEXADECIMAL ORDER Table 3 is a Register Map grouped in hexadecimal address order. Some address locations have been left blank to maintain compatibility with LM86. Addresses in parenthesis are mirrors of “Same As” address for backwards compatibility with some older software. Reading or writing either address will access the same 8-bit register. Table 3.
