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
PSD device. A blank device can be completely
programmed. The JTAG signals (TMS, TCK,
TSTAT, TERR, TDI, TDO) can be multiplexed with
other functions on Port C. Table
4
indicates the
JTAG pin assignments.
In-System Programming (ISP)
Using the JTAG signals on Port C, the entire PSD
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 exe-
cuting the programming algorithms out of the sec-
ondary memory, or SRAM. The secondary
memory can be programmed the same way by ex-
ecuting out of the primary Flash memory. The PLD
or other PSD Configuration blocks can be pro-
grammed through the JTAG port or a device pro-
grammer. Table
5
indicates which programming
methods can program different functional blocks
of the PSD.
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 consump-
tion 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, page 62
for
more details.
