*1 /SRST signal is connected to JP12 and also to POR_B (H24) of i.MX31 and RESET_IN_B (J21). The factory default is
POR_B setting. This does not have to be changed for regular operations.
*2 DE signal is connected to JP16 and further to DE_B (C18) of i.MX31. The factory setting of JP16 is open. Short-circuit this
JP if using DE_B.
