8.5 Register Map

All registers are 8-bit. Table 8-13 shows the memory map. Locations that are marked Reserved read back 0x0000 if they are read by the host. Writing to these locations has no effect.

Instead, they are stored in a temporary register, and used to control the PWM immediately after the control mode is changed to software-DCY control.

0x12	TACH-High-Limit-LByte	R/W	0x00	Low byte of TACH count Limit corresponding to maximum allowed RPM. Since the TACH circuit counts between TACH pulses, a fast fan results in a small measured value. When the measurement is less than this limit, the fan runs above the allowed maximum speed limit.
