+ This requires code in the application that is loaded
+ into Core B. In order to reset, the application needs
+ to install an interrupt handler for Supplemental
+ Interrupt 0, that sets RETI to 0xff600000 and writes
+ bit 11 of SICB_SYSCR when bit 5 of SICA_SYSCR is 0.
+ This causes Core B to stall when Supplemental Interrupt
+ 0 is set, and will reset PC to 0xff600000 when
+ COREB_SRAM_INIT is cleared.
