Table 45.
This command reads the chip identification code and hardware version number. The
firmware must check this information to determine the supported functions and features.
This command accesses the Chip ID Register, which is shown in
Code (Hex): B5 — read chip ID
Transaction — read 2 bytes
Table 47.
This command indicates the sources of interrupts as stored in the 4-byte Interrupt
Register. Each individual endpoint has its own interrupt bit. The bit allocation of the
Interrupt Register is shown in
status in the interrupt service routine. Interrupts are enabled via the Interrupt Enable
Register, see
While reading the interrupt register, read all the 4 bytes completely.
Code (Hex): C0 — read interrupt register
