Register
Legend:
MAR:
IOAR: I/O address register
ETCR: Execute transfer count register
In repeat mode ETCRH is used as the transfer counter while ETCRL holds the initial transfer
count. ETCRH is decremented by 1 at each transfer until it reaches H'00, then is reloaded from
ETCRL. MAR is also restored to its initial value, which is calculated from the DTSZ and DTID
bits in DTCR. Specifically, MAR is restored as follows:
ETCRH and ETCRL should be initially set to the same value.
