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
1.0. In this mode serial I/O1 interrupt have 6 sources; USB in and
out token receive, USB reset, suspend, and resume. The USB/UART
Fig. 23 USB transceiver block diagram
status register (address 0019
16
) 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 22 and
23.
