Parallel JTAG

If I understand the i.mx233 datasheet correctly, the default JTAG mode is the freescale proprietary serial JTAG. To use the Parallel JTAG I need to burn some bits in the OTP. My design doesn't expose the USB port, so I can't burn the bits that way. If PJTAG isn't available by default, how am I suppose to get PJTAG to work?
