Unsuccessful at activating Vaux on development board. Normally un-populated T1 has been updated with PNP: BCP5216 and R22 left in place. Presently using board in debug mode. Board is initialized with following sequence:
0x84 -> INIT register // set Vaux to 5V
0x00 -> WD register // set to normal (debug) mode
0xC0 -> CAN register // enable CAN
0x8C -> REG register // "attempt" to enable Vaux
But no Vaux (5v) voltage at associated dev board pin
Voltage at T1 emitter and base are equal and at supply but no voltage on collector.
I am assuming SPI transfer with 33905 is working since I have CAN activity
Post initialization readback of registers shows:
REG register = 0x08
REG flags = 0x00
Does any one know if I am missing either a hardware mod or software initialization problem?
