hi all

i am facing a problem in st10f273. i am using port pin p4.4 and p4.7 of ST10F273 as general GPIO. but i am not able to toggle these pin using software. i have disabled XI2C and CAN2. my configuration is ODP4.4=0, ODP4.7=0. SYSCAN=08624H and XPERCON=002DH. i am using 8 bit demultiplexed data bus with 4 bit segment addressing.
