When you say that your hardware doesn't support ISP, I
am guessing you just don't have the UART setup to
communicate with the PC.  Can you still pull pin P0.14
low during reset to have the chip enter bootloader
mode anyway?  If so, your code that disabled the JTAG
interface won't get to run (the Philips ISP bootloader
will run instead) and then you can connect through the
JTAG interface and reprogram the chip.

Did you also write 0 to bit 2?  If so, this would
switch the JTAG pins into GPIO mode instead of debug
mode.
