Two IPE signatures, IPE Signature 1 (memory location 0FF88h) and IPE Signature 2 (memory location 0FF8Ah), reside in FRAM and can be used to control the initialization of the IP Encapsulation. Write 0xAAAA to IPE Signature 1 to trigger the evaluation of the IPE Signature 2 as the IPE structure pointer. The following code for CCS is an example:
#define IPE_SIG_VALID 0xFF88
// IPE signature valid flag
#define IPE_STR_PTR_SRC 0xFF8A
// Source for pointer (nibble address) to MPU IPE structure
#pragma RETAIN(ipe_signalValid)
#pragma location=IPE_SIG_VALID
const unsigned int ipe_signalValid = 0xAAAA;
// Locate your IPE structure and it should be placed
// on the top of the IPE memory. In this example, IPE structure
// is at 0xD000
#pragma RETAIN(IPE_stringPointerSourceSource)
#pragma location=IPE_STR_PTR_SRC
const unsigned int IPE_stringPointerSourceSource = (__INSERT_IPE_STRUCT_ADDRESS_(0xD000)__) >> 4;
| Signature | Address | Symbolic Name | Description |
|---|---|---|---|
| IPE Signature 1 | 0FF88h | IPE_SIG_VALID | IPE signature valid flag |
| IPE Signature 2 | 0FF8Ah | IPE_STR_PTR_SRC | Source for pointer (nibble address) to MPU IPE structure |
