DMA0HLT: Halt DMA0 Off-Chip XRAM Access (C8051F060/2/4/6 Only).
0: DMA0 has complete access to off-chip XRAM.
1: Processor core has complete access to off-chip XRAM. DMA0 will wait until this bit is ‘0’
before writing to off-chip XRAM locations.
DMA0XBY: Off-chip XRAM Busy Flag (C8051F060/2/4/6 Only).
0: DMA0 is not accessing off-chip XRAM.
1: DMA0 is accessing off-chip XRAM.
DMA0CIE: Repeat Counter Overflow Interrupt Enable.
0: Disable Repeat Counter Overflow Interrupt.
1: Enable Repeat Counter Overflow Interrupt.
DMA0CI: Repeat Counter Overflow Flag.
0: Repeat Counter Overflow has not occured.
