Reading the ASIC_CONF_REG, IO_CONF_REG and IO_CNTL_REG registers via ETM when the firmware is running shows the same values that are set by the Init_Target() code we have disassembled. When the firmware is running, reading the ARMIO_LATCH_OUT register via ETM returns 0x3F07, i.e., GPIO outputs 0, 1 and 2 (RI, DSR, DCD) are 1s, meaning modem control signals inactive. APCOFF register setting in the Iota ABB is 0x070, same as in our reference fw.
