7.3.3
ETCR is a 16-bit readable/writable register that specifies the number of transfers. The function of
this register is different in normal mode and in block transfer mode.
ETCR is not initialized by a reset or in standby mode.
Normal Mode
ETCRA
In normal mode, ETCRA functions as a 16-bit transfer counter. ETCRA is decremented by 1 each
time a transfer is performed, and transfer ends when the count reaches H'0000. ETCRB is not used
at this time.
ETCRB
ETCRB is not used in normal mode.
