When setting the LPC_TMR32B1->[SIZE=2][COLOR=#0000c0][SIZE=2][COLOR=#0000c0]PWMC [SIZE=3][COLOR=#000000]to 0x11 it will only be sett to 0x1.[/COLOR][/SIZE][/COLOR][/SIZE][/COLOR][/SIZE]

Some suggestion?

Se that 0b did come with the 4.3 gcc

"
Integer constants written in binary are now supported as a GCC extension. They consist of a prefix 0b or 0B, followed by a sequence of 0 and 1 digits.

You can also write your values binary, but I don't want to see things like

value32bit = 0b11001100100101010001001000100111; :eek:

in my code. Perhaps readable for 8-bit values, but not for 32-bit :)

Zero, I think you should send a check to NXP for all the support you're doing here :)

Are we talking about LPC1114?

0x11 is not valid :eek:

If you want to set MAT0 and MAT1 the right value is 0x03 (bit0 + bit1) :)
