In the registers discussed in the following paragraphs, the numbers in the upper right-
hand corner indicate the offset of the register from the base address specified by the
module base address register (MBAR) in the SIM40. The first number is the offset for
channel 1; the second number is the offset for channel 2. The numbers above the register
represent the bit position in the register. The register contains the mnemonic for the bit.
The value of these bits after a hardware reset is shown below the register. The access
privilege is shown in the lower right-hand corner.
6.7.1 Module Configuration Register (MCR)
The MCR controls the DMA channel configuration. Each DMA channel has an MCR. This
register can be either read or written when the channel is enabled and is in the supervisor
state. The MCR is not affected by a CPU32 RESET instruction.

ADDRESS
A CPU32 RESET instruction will not affect the MCR but will
reset all other registers in the DMA module as though a
hardware reset occurred. The term DMA is used to reference
either channel 1 or channel 2, since the two are functionally
equivalent.
