Hi，

MC56F84789 uses jtag for on chip emulation and download.

while for MC56F84789, some jtag pin is multiplexed with GPIO. see datasheet, page 17,18.

http://www.nxp.com/files/dsp/doc/data_sheet/MC56F844XX.pdf?fasp=1&WT_TYPE=Data%20Sheets&WT_VENDOR=FREESCALE&WT_FILE_FORM…

if you defile the related jtag pin as GPIO, the jtag feature can not work normal.

Have a great day,
Jennie Zhang
