7.3.3
An execute transfer count register (ETCR) is a 16-bit readable/writable register that specifies the
number of transfers to be executed. The functions of these registers differ between normal mode
and block transfer mode.
ETCRA
ETCRB: Is not used in normal mode.
In normal mode ETCRA functions as a 16-bit transfer counter. The count is decremented by 1
each time one transfer is executed. The transfer ends when the count reaches H'0000. ETCRB is
not used.
