I'm hoping someone can explain how the LPC11C24 part can have 11 PWM channels (according to the Parametric search on NXP.com).  I've read the user manual and I can only come up with 9 because each timer needs one of its match registers to set the PWM cycle length.  Is the Parametric search wrong or is it me?


I/O PIN       MATCH REG.   *=PWM cycle length register
