2.8
Page register
The 8-bit Page register expands the address range of the MCU by up to 256 times. The
paged address can be used as part of the address space to access external memory and
peripherals, or internal memory and I/O. The Page register can also be used to change the
address mapping of the Flash memory blocks into different memory spaces for IAP.

Power Management Unit (PMU)
The Power Management Unit (PMU) gives the user control of the power consumption on
selected functional blocks based on system requirements. The PMU includes an Automatic
power-down (APD) Unit that turns off device functions during MCU inactivity. The APD Unit
has a Power-down mode that helps reduce power consumption.
The PSD also has some bits that are configured at run-time by the MCU to reduce power
consumption of the CPLD. The Turbo bit in PMMR0 can be reset to '0' and the CPLD latches
its outputs and goes to Standby mode until the next transition on its inputs.
Additionally, bits in PMMR2 can be set by the MCU to block signals from entering the CPLD
to reduce power consumption. See Section 20: Power management for more details.
