Universal serial bus (USB) mode
By setting bits 7 and 6 of the serial I/O1 control register (address
001A16) to “11”, the USB mode is selected.
This mode conforms to “Low Speed device” of USB Specification
1.1. In this mode serial I/O1 interrupt have 6 sources; USB in and
out token receive, setup token receive, USB reset, suspend, and

resume. The USB status/UART status register functions as the USB
status register (USBSTS).There is the USBVREFOUT pin for the USB
reference voltage output, and a D-line with 1.5 k
external resistor
can be pull up. USB mode block and USB transceiver block shown
in figures 25 and 26.
