(UART mode). Bits TXD_EN and RXD_EN in the CARKIT_CTRL
register (see

0b — Disable carkit mode
1b — Enable carkit mode
3-pin full-speed low-speed serial mode: Changes the ULPI
interface to a 3-bit serial interface. The ISP1705 will automatically
clear this bit when 3-pin serial mode is exited.
0b — Full-speed or low-speed packets are sent using the parallel
interface
1b — Full-speed or low-speed packets are sent using the 3-pin
serial interface
6-pin full-speed low-speed serial mode: Changes the ULPI
interface to a 6-bit serial interface. The ISP1705 will automatically
clear this bit when 6-pin serial mode is exited.
0b — Full-speed or low-speed packets are sent using the parallel
interface
1b — Full-speed or low-speed packets are sent using the 6-pin
serial interface
