The voltage regulator can generate V
DDINT
at levels of 1.00 V to 1.20 V with –5% to +5% tolerance when VRCTL is programmed with the bfrom_SysControl() API. This
specification is only guaranteed when the API is used.

Bidirectional balls (PF15–0, PG15–0, PH15–0) and input balls (RTXI, TCK, TDI, TMS, TRST, CLKIN, RESET, NMI, and BMODE3–0) of the ADSP-BF52x processors are
2.5 V tolerant (always accept up to 2.7 V maximum V

). Voltage compliance (on outputs, V
OH
) is limited by the V
