Looking at the lpc8xx.h in CMSIS I found a problem.

The MRT definitions in the file contain:

typedef struct {
__IO uint32_t INTVAL; 
__IO uint32_t TIMER;         
__IO uint32_t CTRL;          
__IO uint32_t STAT;          
} MRT_Channel_cfg_Type;

typedef struct {
  MRT_Channel_cfg_Type Channel[4]; 
   uint32_t Reserved0[1]; 
  __IO uint32_t IDLE_CH; 
  __IO uint32_t IRQ_FLAG; 
} LPC_MRT_TypeDef;

but this places the IRQ_FLAG at address 0x4000 4048. The user manual mentions 0x4000 40f8
This means that the Reserved0[1] should be Reserved0[45] instead - and nog magically my code works and that there is a bug in the NXP supplied lpc8xxx.h

Thank you for your feedback.
I believe you are correct. I will report this to our software team.
