hello, I'm a little confused about leaving the program mode of the 16F690: as 41204G.pdf states: To prevent a device configured with INTOSC and internal MCLR from executing after exiting Program/ Verify mode, VDD needs to power-down before VPP. See Figure3-3 for the timing. which is in contra-diction with fig 3-3. So which of the 2 is true ? thanks, Stef Mientki -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
