TC654/TC655
6.0
REGISTER SET
The TC654/TC655 devices contain 9 registers that pro-
vide a variety of data and functionality control to the
outside system. These registers are listed below in
Table 6-1. Of key importance is the command byte
information, which is needed in the read and write pro-
tocols in order to select the individual registers.
TABLE 6-1:
COMMAND BYTE ASSIGNMENTS
6.1
RPM-OUTPUT1 & RPM-OUTPUT2
Registers (RPM1 & RPM2)
As discussed in Section 4.7, fan current pulses are
detected at the SENSE1 and SENSE2 inputs of the
TC654/TC655 device. The current pulse information is
used to calculate the fan RPM. The fan RPM data for
fans 1 & 2 is then written to registers RPM1 and RPM2,
respectively. RPM1 and RPM2 are 9-bit registers that
provide the RPM information in 50 RPM (8-bit) or
25 RPM (9-bit) increments. This is selected via RES (bit
6<0>) in the Configuration Register, with ‘0’ = 50 RPM
and ‘1’ = 25 RPM. The default state is zero (50 RPM).
The maximum fan RPM value that can be read is
12775 RPM. If this value is exceeded, R2CO (bit 4<0>)
and R1CO (bit 3<0>) in the Status Register will be set
to a '1' to indicate that a counter overflow of the respec-
tive RPM register has occurred. Register 6-1 shows the
RPM output register 9-bit format.
