6.1.4
Droop function adjustment (DRP_ADJ)
This command allows to adjust the slope for the output voltage load line once the external
components are defined by modifying the kDRP and kDRPNB parameters defined in
Section 7.3 and Section 7.6.
stream.
6.1.5
Power management flags
This command allows to set several flags to configure L6717 power management.
The flags allows to define:
– PSI_A. This flag defines phase shedding strategy adopted when CPU asserts PSI_L
by SVI bus. Set PSI_A = 0b (default) to program the device to work in single phase or
set PSI_A = 1b to program two phase mode.
The selected strategy applies also to DPM mode.
See Section 5.4.3 for details about PSI management and light-load efficiency
optimizations. See Section 6.2 for details about DPM.
– PSI_EN. This flag defines whether to enable or not the PSI_L management. Default is
to manage PSI_L flag assertion through SVI bus (PSI_EN = 1b).
– DPM_ON. This flag defines whether to enable or not the DPM mode. The strategy
adopted by DPM is defined through the PSI_A flag. See Section 6.2 for details about
DPM. DPM is disabled by default (DPM_ON = 0h).
– DPMTH. Allow to program up to 4 different strategies for DPM mode by properly
stream.
