USB registers
A first MOVX@DPTR instruction enables module selection (via DPH) and command transmission. A second MOVX
communicates the data (read or write).

Notes
1. The GET_FRAMENUMBER command returns the frame number of the last received Start Of Frame (SOF). The
frame number is 11 bits wide; therefore two consecutive reads are needed to get the complete value. The first byte
provides the LSBs; the second byte (bits 0 to 2) provides the 3 MSBs. Note: it is possible to read the first byte only.
2. The GET_CHIPID command is followed by two reads since the chip identification is 16 bits wide (see Tables 55
and 56).
3. The RW_DATA command can be followed by up to ‘n + 2’ bytes read or write (n is the number of data bytes in the
selected EP buffer). With read, it returns the contents of the selected EP data buffer. With write, it loads the data
buffer of the selected EP.
