C.1.3 Test Channel RAM
1. To test the channel’s RAM, follow these steps:
2. Write the desired window size to the BankSize register (refer to Section 3.4.5,
BankSize Register, for details).
3. Write 0x40 (MemEn) to the Control Register.
4. Set the Bank Address Register (refer to Section 3.4.4, Bank Address Register,
for details).
5. Fill the shared memory with a test pattern.
Note
We recommend using a test pattern with a unique value for each word in
a given bank. In C language this could be:
~offset + bank.
6. Repeat steps 3-4 for all memory banks.
7. Verify the test pattern.
