Table 2-15 • Memory Map for RTC in ACM Register and Description
Voltage Regulator and Power System Monitor (VRPSM)
The VRPSM macro controls the power-up state of the FPGA. The power-up bar (PUB) pin can turn on
the voltage regulator when set to 0. TRST can enable the voltage regulator when deasserted, allowing
the FPGA to power-up when user want access to JTAG ports. The inputs VRINITSTATE and
RTCPSMMATCH come from the flash bits and RTC, and can also power up the FPGA.
