LPC1315/16/17/45/46/47
32-bit ARM Cortex-M3 microcontroller
The RESET pin selects between the JTAG boundary scan (RESET = LOW) and the ARM
SWD debug (RESET
= HIGH). The ARM SWD debug port is disabled while the
LPC1315/16/17/45/46/47 is in reset.
Remark: Boundary scan operations should not be started until 250 s after POR, and the
test TAP should be reset after the boundary scan. Boundary scan is not affected by Code
Read Protection.
Remark: The JTAG interface cannot be used for debug purposes.
