DMA Interrupt Reason register (address: 50h)
This 2-byte register shows the source(s) of DMA interrupt. Each bit is refreshed after
a DMA command has been executed. An interrupt source is cleared by writing logic 1
to the corresponding bit. When reading, AND the value of the bits in this register with
the value of the corresponding bits in the DMA Interrupt Enable register.
The bit allocation is given in
Table 56
.

Description
ENDIAN[1:0]
These bits determine whether the data bus is swapped between the
internal RAM and the DMA bus. This only applies for GDMA (slave)
mode.

Remark:
While operating with the 8-bit data bus, bits ENDIAN[1:0]
should be always set to logic 00.
