USB INTERFACE (Cont’d)
Bit 0 = SOFP_ENABLE: Start-Of-Frame Pulse
Enable.
Set by software to enable the use of the USBSOF
alternate output function.
1: USBSOF alternate function enabled
0: USBSOF output disabled
USBSOF outputs a 333.33 ns long pulse at each
frame start (actually 10 bits before the SOF packet
expected start). This pulse is not generated until
two SOF packets are received after any USB reset
or USB resume (frame timer locking) and they stop
as soon as the suspend condition is entered
(TIM_SUSP bit in USBCTLR register).
MIRROR REGISTER A (MIRRA)
R246 - Read/Write
Register page: 60
Reset value: xxxx xxxx (xxh)
Bit 7:0 = MIRA[7:0] Mirror register A, bits 7-0.
This register acts as a bit mirroring location where
software can write a byte and read it back with the
LSB and MSB position swapped.
