In repeat mode, ETCRH functions as an 8-bit transfer counter and ETCRL holds the initial transfer
count. ETCRH is decremented by 1 each time one transfer is executed. When ETCRH reaches
H'00, the value in ETCRL is reloaded into ETCRH and the same operation is repeated.
The ETCRs are not initialized by a reset or in standby mode.
