12.3.5
Read Chip ID
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
Table 47
.
Code (Hex): B5 —
read chip ID
Transaction —
read 2 bytes
12.3.6
Read Interrupt Register
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
Table 49
. Bit BUSTATUS is used to verify the current
bus status in the interrupt service routine. Interrupts are enabled via the Interrupt
Enable Register, see
Section 12.1.5
.
Code (Hex): C0 —
read interrupt register
Transaction —
read 4 bytes
