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.
