12.3.3
Write/Read Scratch Register
This command accesses the 16-bit Scratch Register, which can be used by the
rmware to save and restore information, for example, the device status before
powering down in ‘suspend’ state. The register bit allocation is given in Table 40.
Code (Hex): B2/B3 — write/read Scratch Register
Transaction — write/read 2 bytes
12.3.4
Read Frame Number
This command returns the frame number of the last successfully received SOF. It is
followed by reading one or two bytes from the Frame Number Register, containing the
frame number (lower byte rst). The Frame Number Register is shown in Table 42.
Remark: After a bus reset, the value of the Frame Number Register is undened.
