7. DMA Controller
(channel 0) or by a conversion-end interrupt from the A/D converter, and as a destination address
register otherwise.
The IOAR value is held fixed. It is not incremented or decremented when a transfer is executed.
The IOARs are not initialized by a reset or in standby mode.

Execute Transfer Count Registers (ETCR)
An execute transfer count register (ETCR) is a 16-bit readable/writable register that specifies the
number of transfers to be executed. These registers function in one way in I/O mode and idle
mode, and another way in repeat mode.

Transfer counter
In I/O mode and idle mode, ETCR functions as a 16-bit counter. The count is decremented by
1 each time one transfer is executed. The transfer ends when the count reaches H'0000.
