Power Management API Reference
adi_pwr_Init
Description
This function initializes the power management module. The following
values must be set for successful initialization:
Processor variant
Package kind
Core voltage (V
DDINT
External voltage (V
CLKIN
These are communicated to the
pointer to a table of command-value pairs, terminated with the
ADI_PWR_CMD_END
For example, the following
Lite values:
ADI_PWR_COMMAND_PAIR ezkit_init[] = {
{ ADI_PWR_CMD_SET_PROC_VARIANT, ADI_PWR_PROC_BF533SKBC600 },
{ ADI_PWR_CMD_SET_PACKAGE,
{ ADI_PWR_CMD_SET_VDDEXT,

the core by an external voltage regulator. The internal voltage
regulator is bypassed. Its absence in the command table implies
that the internal regulator is to be used. An external voltage regu-
lator is required for the ADSP-BF533SKBC750 processor, as the
internal voltage regulator cannot supply the 1.4 V required for
the processor to run at 750 MHz.
