PS014004-1106
Free Running Counter I/O Address = 18H
DMA Source Address Register, Channel 0L
Mnemonic FRC: 18H
If data is written into the free running counter, the interval of DRAM refresh cycle and baud
rates for the ASCI and CSI/O are not guaranteed. In IOSTOP mode, the free running counter
continues counting down. It is initialized to FFH, during RESET.

transfers. The register contains 20 bits and can specify up to 1024 KB memory addresses or
up to 64 KB I/O addresses. Channel 0 source can be memory, I/O, or memory mapped I/O.
For I/O, the most significant bits of this register identify the
signal.
Mnemonic SAR0L: Address 20h
SAR0: I/O ADDRESS = 20h to 22h
