a
a.
Run time selection is via the SCC2 registers (see Section 5). If the reset value of CFG0 is 0, run
time selection is disabled after reset. To enable run time selection, configure the SCC2 to any infra-
red mode. Once this is done, run time selection is enabled. If the reset value of CFG0 is 1, run time
selection is enabled immediately after reset.
