5.7 In-System Programming
Using the JTAG signals on Port C, the entire PSD8XXF device can be programmed or
erased without the use of the microcontroller. The main Flash memory can also be
programmed in-system by the microcontroller executing the programming algorithms out
of the Flash Boot memory, or SRAM. The Flash Boot memory can be programmed the
same way by executing out of the main Flash memory. The PLD logic or other PSD8XXF
configuration can be programmed through the JTAG port or a device programmer. Table 4
indicates which programming methods can program different functional blocks of the
PSD8XXF.

5.8 Power Management Unit
The Power Management Unit (PMU) in the PSD8XXF gives the user control of the
power consumption on selected functional blocks based on system requirements. The
PMU includes an Automatic Power Down unit (APD) that will turn off device functions due
to microcontroller inactivity. The APD unit has a Power Down Mode that helps reduce
power consumption.
The PSD8XXF also has some bits that are configured at run-time by the MCU to reduce
power consumption of the CPLD. The turbo bit in the PMMR0 register can be turned off
and the CPLD will latch its outputs and go to sleep until the next transition on its inputs.
Additionally, bits in the PMMR2 register can be set by the MCU to block signals from
entering the CPLD to reduce power consumption. See section 9.5.
