Programmable Registers
in the order they appear in the register map. Once the pointer's contents have been loaded
into the PXP's registers, the NEXT_IRQ interrupt will be issued (see the PXP_STATUS
register).
EXAMPLE
// create register command structure in memory
// initialize control structure for frame 0
// initialize control structure for frame 1
// poll until a command isn't queued
// poll until first command clears
