ROM-monitor hardware resource usage
The ROM-monitor uses the following hardware resources of the LPC210x microcontroller:
• UART0
• VIC vector 0
• 4 Kbytes Flash ROM memory in the address range 0x0-0x00000FFF
• 1 Kbyte RAM memory in the address range 0x40000000-0x400003FF.
Your application must not use any of the above resources. This means that:
• all UART0 registers must be untouched by user code.
• pclk must be kept at the XTAL frequency divided by 4. This is the default after reset. If the PLL configuration and
VPBDIV is altered this ratio must be maintained.
• PINSEL0: Bits 0:3 must be set to 0x5.
