Both the DONE and INIT pins go Low, followed by the INIT pin going High indicating the start of configuration is requested. The state machine in the CPLD recognizes this event and begins to set up the SPI memory for a read operation. The operation begins by bringing spi_sn Low, followed by passing CCLK through to spi_c and

WebMay 27, 2024 · Re: Connection for unused dual purpose pins of CPLD Hi, I usually don't externally connect unused pins to GND (or any other signal). You are more flexible to config these pins by program. ESD means "electrostatic discharge". If you fear that ESD may harm unused pins you should fear that ESD may harm used pins, too. WebJan 29, 2014 · A cheaper option than BP is to get another Lattice breakout board and use it as a programmer. You can put the CPLD in JTAGENB mode and pass through the JTAG signals from FTDI to any pin on the PLD at any voltage level. A $30 alternative to the $35 BP and $190 Lattice programmer that still works with built-in IDE tools. gabor women\u0027s fashion low-top sneakers https://htctrust.com
