20.4.1 Test Mode Settings
The RCAN-TL1 has various test modes. The register TST[2:0] (MCR[10:8]) is used to select the
RCAN-TL1 test mode. The default (initialised) settings allow RCAN-TL1 to operate in Normal
mode. The following table is examples for test modes.
Test Mode can be selected only while in configuration mode. The user must then exit the
configuration mode (ensuring BCR0/BCR1 is set) in order to run the selected test mode.
