CONFIG1 in CPU mode
Config1/PSI1 is a multi-functional pin, during startup it is used as pinstrapping.
Setting the device in CPU mode it is possible to select:
a)
TMAX. Maximum temperature can be set from 90 °C, 100 °C, 110 °C and 120 °C.
b)
IMAX. Maximum current for the multi-phase rail can be selected by pinstrapping
as required by Intel specifications. The maximum current can be selected by 4
values which can change depending on the number of the phases selected (see
Section 6.5).
c)
Jmode. It is possible to set Jmode (see Section 6.4). In MRO mode the single-
phase rail remains off and Jmode bitstrapping is used to change the number of
switching phases (see Table 7).
