hello.....


I have recently realized that the LPC43xx Cortex-M0APP does not support TIMER1 and TIMER2 interrupt vectors (refer to UM10503.pdf: Chapter 8.6.2, page 103 of 1420).  Indeed, these interrupting devices (TIMER1 and TIMER2) are supported by the Cortex-M0SUB.  The LPC43xx does not contain a third core (Cortex-M0SUB)  However, I have read in UM10503.pdf (LPC43xx ARM Cortex-M4/M0 multi-core microcontroller, Rev 1.8, 28-jan-2014) that most all the peripherals are supported by both cores.  I take this understanding to include the TIMERx peripheral. 

If the Cortex-M0APP does support this subsystem, how does one get access to the interrupts for all four TIMERs from within the Cortex-M0APP?

Thanks, in advance, for your assistance.
