/**
 * This is based on some quick but sound experiments on PP5022C.
 * CPU/COP_CTL bitmap:
 *   [31] - sleep until an interrupt occurs
 *   [30] - wait for cycle countdown to 0
 *   [29] - wait for cycle countdown to 0
 *          behaves identically to bit 30 unless bit 30 is set as well
 *          in which case this bit is cleared at the end of the count
 *   [28] - unknown - no execution effect observed yet
 *   [27] - begin cycle countdown
 * [26:8] - semaphore flags for core communication ?
 *          no execution effect observed yet
 *          [11:8] seem to often be set to the core's own ID
 *                 nybble when sleeping - 0x5 or 0xa.
 *  [7:0] - W: number of cycles to skip on next instruction
 *          R: cycles remaining
 * Executing on CPU
 *   CPU_CTL = 0x68000080
 *   nop
 * stalls the nop for 128 cycles
 * Reading CPU_CTL after the nop will return 0x48000000
