Power saving features
To reduce power consumption STULPI01 implements 2 low-power modes of operation.
More information on these modes can be found in following paragraphs.
Modes of operation
ULPI synchronous mode
STULPI01 transceiver supports SDR mode operation (12-pin interface). The selection of
SDR mode is performed during startup reset procedure.
6-pin FS/LS serial mode
This mode is entered by writing to corresponding bit in the Interface Control register.
3-pin FS/LS serial mode
This mode is entered by writing to corresponding bit in the Interface Control register.
Car kit (UART) mode
This mode is entered by writing to the car kit mode bit in the interface control register.
STULPI01 does not implement all features of car kit mode, only the UART functionality is
preserved.
1. Low-power mode, which is defined in ULPI specification.
2. Power-down mode to save more power in case USB function is not needed.
