JTAG Port
In-System Programming (ISP) can be performed
through the JTAG signals on Port C. This serial in-
terface allows complete programming of the entire
PSD8XXFX device. A blank device can be com-
pletely programmed. The JTAG signals (TMS,
TCK, TSTAT, TERR, TDI, TDO) can be multi-
plexed with other functions on Port C. Table 3 in-
dicates the JTAG pin assignments.
In-System Programming (ISP)
Using the JTAG signals on Port C, the entire
PSD8XXFX device can be programmed or erased
without the use of the MCU. The primary Flash
memory can also be programmed in-system by
the MCU executing the programming algorithms
out of the secondary memory, or SRAM. The sec-
ondary memory can be programmed the same
way by executing out of the primary Flash memo-
ry. The PLD or other PSD8XXFX Configuration
blocks can be programmed through the JTAG port
or a device programmer. Table 4 indicates which
programming methods can program different func-
tional blocks of the PSD8XXFX.
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 PSD8XXFX also has some bits that are con-
figured 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 sleep 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. Please see the sec-
tion entitled “POWER MANAGEMENT” on page
58 for more details.
