6.2.5.2. Rotate Priority Mode
In Rotate Priority Mode (PRTMOD=1), the IPEN and IPACT bits have no function (i.e. can be ignored).
W90N745 uses a round robin arbitration scheme ensures that all bus masters have equal chance to gain
the bus and that a retracted master does not lock up the bus.
6.2.6 Power Management
W90N745 provide three power management scenarios to reduce power consumption. The
peripherals’ clocks can be enabled / disabled individually by controlling the co-responding bit in
CLKSEL control register. Software can turn-off the unused modules’ clocks to saving the unnecessary
power consumption. It also provides idle and power-down modes to reduce power consumption.
