ST92163 - USB PERIPHERAL (USB)

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

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.

MIRROR REGISTER B (MIRRB)

R247 - Read/Write

Reset value: xxxx xxxx (xxh)

Bit 7:0 = MIRB[7:0]

Mirror register B, 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.
