The self-test destroys the content of the tested memory. So, it could be used after sys-
tem reset, during system initialization. Only one self-test (transmitters and receivers)
can be performed after a reset. If the self-test must be restarted, the reset must be acti-
vated (then released) before the new self-test start.
To program the self-test:
1. If the receiver self-test will be used:
2. If receiver self-test will be used and CLK-SYS is > 10 MHz:
3. Start self-test:
To read the self-test result, the user must:
1. poll the self-test register and wait for an end of test set to 1 (bits 8 to 10, bit 14)
2. read the self-test register again to have a valid result on bits 11, 12, 13, 15
bit 13: Result of Transmitter 3 self-test:
bit 14: 0: Receiver Label Control Matrix self-test is running,
bit 15: Result of receiver LCM self-test:
set to 1 LCMWE bits (for all receivers).
set to self-test register bit 5.
set to 1 self-test register bit 6 for Transmitter test,
set to 1 self-test register bit 7 for Receiver RAM test.
At this point, self-test is running. The test duration is:
710 CLK-SYS periods for Transmitter self-test,
2820 CLK-SYS periods for Receiver RAM test if self-test register bit 5 is 0,
5640 CLK-SYS periods for Receiver RAM test if self-test register bit 5 is 1.
then,
according to the tests which end at point 1.
