Name
For Synchronous DMA mode, the setting of these bits
determines the minimum write strobe cycle time (CT). The
DMARDY#-to-STOP (RP) time is also determined by the
setting of these bits.
PCB1 = 0 (33 MHz clk)
00 = CT 4 clocks, RP 6 clocks
01 = CT 3 clocks, RP 5 clocks
10 = CT 2 clocks, RP 4 clocks
11 = Reserved
PCB1 = 1 (66 MHz clk)
00 = Reserved
01 = CT 3 clocks, RP 8 clocks
10 = CT 2 clocks, RP 8 clocks
