PRELIMINARY
Notice: This is not a final specification.
Some parametric limits are subject to change.
Universal serial bus (USB) mode
By setting bits 7 and 6 of the serial I/O1 control register (address
001A
16
) 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 5 sources; USB in and
out token receive, USB reset, suspend, and resume. The USB
Fig. 26 USB transceiver block diagram
status/UART status register functions as the USB status register
(USBSTS).There is the USBV
REFOUT
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 show in figures 25
and 26.
