8.3.3.3 Interrupt modes

Two interrupt modes are available: single vector,

where the application software has to poll the USB

registers to determine which event required its at-

tention, and multi-vector, where a specific interrupt

vector is used for each endpoint. Special support

is offered to isochronous transfers, implementing a

swapped DMA buffer usage.

8.3.3.4 Suspend mode

The unit can be placed in low-power mode (SUS-

PEND mode), by writing in a control register. At

this time, all static power dissipation is avoided,

except for the generation of the 3.3V supply for the

external pull-up resistor. The detection of activity

at the USB inputs while in low-power mode wakes

the device up asynchronously. A special interrupt

source, ESUSP, is connected directly to a wake-

up line so as to allow the ST9 to exit from HALT

condition.
