2.0 LM64 Registers
The following pages include: Section 2.1, a Register Map in Hexadecimal Order, which shows a summary of all registers and their
bit assignments, Section 2.2, a Register Map in Functional Order, and Section 2.3, a detailed explanation of each register. Do not
address the unused or manufacturer’s test registers.
2.1 LM64 REGISTER MAP IN HEXADECIMAL ORDER
The following 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.
