Peripheral Identification Register (PID)
SRIO Registers
The peripheral identification register (PID) is a read-only register that contains the ID and ID revision
number for that peripheral. The PID stores version information used to identify the peripheral. Writes have
no effect to this register. The values are hard coded and will not change from their reset state.
The peripheral ID register (PID) is shown in
Figure 63
and described in
Table 41
.
