LPC122x M0 debugging
When viewing the SPP0 registers in "Peripherals" in Eclipse (on a breakpoint within the interrupt routine), the interrupt status registers SSPRIS and SSPMIS do not show the correct value. IE the bits are not set to reflect what the source of the SSP interrupt was. However reading the same register in C code works correctly EG status= LPC_SSP->RIS; shows the the bit(s) set that invoked the interrupt. Refresh does not correct this. The lpcxpresso version is v5.2.4 [Build 2122] [2013-04-29] for Linux.
