Description
CPU Data Read Interrupt flag
0 = DCCPU has not been read since the clearing
of this bit.
1 = DCEMU has been read.
This bit is cleared by writing this bit to 0.
Emulator Data Dirty
0 = DCEMU has not been written to since last read
from CPU.
1 = DCEMU contains a new data value.
This bit is cleared by reading DCEMU.
CPU Data Dirty
0 = DCCPU has not been written to since last read
from emulator.
1 = DCCPU contains a new data value.
This bit is cleared by reading DCCPU.
Description
Reserved
These bits are reserved, and will always read
as 0
DCCPU Interrupt Mask
0 = DCCPU interrupts are disabled.
1 = DCCPU interrupts are enabled.
DCEMU Interrupt Mask
0 = DCEMU interrupts are disabled.
1 = DCEMU interrupts are enabled.
