Chapter 11: LPC43xx/LPC43Sxx Configuration Registers (CREG)
11.4.2 CREG1 control register
Remark:
The wake-up from deep-sleep using USB0 and USB1 is supported only in flash
based devices and is not supported in flashless devices.
11.4.3 ARM Cortex-M4 memory mapping register
The reset value for this register depends on the execution of the boot loader. See
. All memory mapped addresses must be located on a 4 kB boundary.
11.4.4 CREG5 control register
Use this register to disable the JTAG for the M4 main core and the M0 co-processors. By
default the JTAG access is enabled unless an AES key is programmed and the device is a
secure device.
Remark:
Disabling the JTAG can only be reversed by resetting the part through any
available reset.
