Signal Description
Bus
to
Access to the UDP is via the APB bus interface. Read and write to the data FIFO are done by
reading and writing 8-bit values to APB registers.
The UDP peripheral requires two clocks: one peripheral clock used by the Master Clock domain
(MCK) and a 48 MHz clock (UDPCK) used by the 12 MHz domain.
A USB 2.0 full-speed pad is embedded and controlled by the Serial Interface Engine (SIE).
The signal external_resume is optional. It allows the UDP peripheral to wake up once in system
mode. The host is then notified that the device asks for a resume. This optional feature must
also be negotiated with the host during the enumeration.
