NOTES: A. During programming activity and when blowing the JTAG enable fuse, the TDI/VPP terminal is used to apply the correct voltage
source. The TDO/TDI terminal is used to apply the test input data for JTAG circuitry.
B. The TDI/VPP terminal of the ’P325A and ’E325A does not have an internal pullup resistor. An external pulldown resistor is
recommended to avoid a floating node which could increase the current consumption of the device.
C. The TDO/TDI terminal is in a high-impedance state after POR. The ’P325A and ’E325A needs a pullup or a pulldown resistor to avoid
floating a node which could increase the current consumption of the device.
