signaling to use. OLD_JTAG = 0x0 Use six-wire parallel JTAG mode. SERIAL_JTAG = 0x1 Use
one-wire serial JTAG mode.
It is good idea to check the datasheet of the iMX233 processor for all the options in the digital
control block. The processor's datasheet should be always the first piece of paper you consult when
dealing with electronics.
