Note 15:
For Register 0x1A the Power-On-Reset for the five LSB’s are the logic states present on the 5 GPIOx pins.
Note 16:
For Register 0x1B the Power-On-Reset for the five LSB’s are the logic states present on the 5 GPDx pins.
2.3 LM64 INITIAL REGISTER SEQUENCE AND REGISTER DESCRIPTIONS IN FUNCTIONAL ORDER
The following is a Register Map grouped in functional and sequence order. Some address locations have been left blank to
maintain compatibility with LM86. Addresses in parenthesis are mirrors of named address for backwards compatibility with some
older software. Reading or writing either address will access the same 8-bit register.
2.3.1 LM64 Required Initial Fan Control Register Sequence
Important!
The BIOS must follow the sequence below to configure the following Fan Registers for the LM64 before using any of
the Fan or Tachometer or PWM registers:
Step
1
[Register]
HEX
and Setup Instructions
[4A] Write bits 0 and 1; 3 and 4. This includes tach settings if used, PWM internal clock select (1.4 kHz or
360 kHz) and PWM Output Polarity.
[4B] Write bits 0 through 5 to program the spin-up settings.
[4D] Write bits 0 through 4 to set the frequency settings. This works with the PWM internal clock select.
Choose, then write,
only one
of the following:
A. [4F–5F] the Lookup Table,
or
B. [4C] the PWM value bits 0 through 5.
If Step 4A, Lookup Table, was chosen and written then write [4A] bit 5 = 0.
All other registers can be written at any time after the above sequence.
