Description www.ti.com 5.1.2 PMBus Standard PMBus interface is provided to the sequencer from the onboard USB-PMBus circuitry. PMBus addressing is set using the J13 jumper block for ADDRSENS1 and ADDRSENS0. respectively. ADDRx = 8 and ADDRx = 5 positions for each are provided. The EVM comes with PMBus address set to 101 decimal. PMBus Address (decimal) = 12 x ADDR1 + ADDR0 jumper block setting. 5.1.3 JTAG Standard JTAG programming interface is provided to the sequencer through the J6 connector.
