NS9750 Hardware Reference
// Examples:
//
// ew MAJIC_ON_STOP_CMD = 1, @$ucd_rd8, FFF00003
//
// Defines an On-Stop command that reads the byte at 0xFFF00003 upon
// stopping.
//
// ew MAJIC_ON_STOP_CMD = 1, @$ucd_rmw16, 80000000, C00, F00
//
// Defines an On-Stop command that reads a 16-bit value from 80000000,
// masks off bits 11..8, sets those bits to 1100, and writes the result
// back to 80000000.
//
// ew MAJIC_IDLE_MODE_CMD = 0n250, @$ucd_wr32, 0x40000000, 0n5000
//
// Defines the Idle-Mode command that writes the 32-bit value 5000 (decimal)
// to the register at 0x40000000 every 250 milliseconds.
//
// ew MAJIC_ON_STOP_CMD= 0
// ew MAJIC_IDLE_MODE_CMD= 0
//
// Disables the On-Stop and Idle-Mode command descriptors.
