UM0193 jumper settings 29/35 appendix c jumper settings ta bl e 1 5 describes the jumper settings for the armic30 evaluation board. table 15. armic30 jumper settings jumper function description j32 +5v dc application voltage supply to dc/dc converter (u6) when pins 1 and 2 are connected, the +5v dc voltage supply is connected. otherwise, it is disconnected. j33 +3.3v dc application part supplying connection to dc/dc converter (u6) reference pin or linear voltage regulator (u7) when pins 1 and 2 are connected, the dc/dc converter (u6) reference pin supplies the 3.3v application part voltage. when pins 2 and 3 are connected, the linear voltage regulator (u7) supplies the 3.3v application part voltage. j34 gnd test point both sides are connected to gnd. j5 mcu boot mode selection (m0 pin) (1) when pins 1 and 2 are connected, the m0 pin is connected permanently to gnd. when pins 2 and 3 are connected, the m0 pin is connected permanently to +5v dc. j6 mcu boot mode selection (m1 pin) (1) when pins 1 and 2 are connected, the m1 pin is connected permanently to gnd. when pins 2 and 3 are connected, the m1 pin is connected to +5v dc during a microcontroller reset. after a reset, it is tied to gnd. j35 rs-232 loop selection when pins 1 and 2 are connected, the rs-232 is in loop mode and the rx and tx lines are connected together (for hardware or software testing). otherwise, the rs-232 connection is in normal mode j10 and j13 rs-485 bus termination when pins 1 and 2 are connected, the rs-485 bus is terminated. (node is at the end of the rs- 485 bus.) (2) otherwise, the rs-485 bus is unterminated. j14 can channel termination when pins 1 and 2 are connected, the can bus is terminated. (3) otherwise, the can bus is unterminated. j19, j21 and j23 +5v dc connection (to pin number 1 of corresponding general purpose / motor control connector) when pins 1 and 2 are connected, the corresponding +5v dc supply is connected. otherwise, it is disconnected. j16 +5v dc connection to pin number 1 of the 8-bit input/general purpose connector (j17) when pins 1 and 2 are connected, the +5v dc supply is connected. otherwise, it is disconnected.
jumper settings UM0193 30/35 j25 gnd connection to pin number 2 of the 8-bit input/general purpose connector (j17) when pins 1 and 2 are connected, the gnd supply is connected. otherwise, it is disconnected. j26 +5v dc connection to pin number 1 of the 8-bit output/general purpose connector (j27) when pins 1 and 2 are connected, the +5v dc supply is connected. otherwise, it is disconnected. j29 gnd connection to pin number 2 of the 8-bit output/general purpose connector (j27) when pins 1 and 2 are connected, the gnd supply is connected. otherwise, it is disconnected. 1. for detailed information about boot selection m odes, please refer to str730 reference manual. 2. please check the termination resistors values (r25, r26 and r28) for your rs-485 physical layer. 3. can bus is terminated by resistor r33 (120 ? ). table 15. armic30 jumper settings (continued) jumper function description
