Hello.
I have problem with Monitor Mode in MC68HC908GP32. I try to programme this uC so I use PROG08SZ programmer (on Windows 2003). I made Normal Monitor Mode Circuit from AN2317/D Application Note (page 9):

but I used a 8 MHz oscillator. My GP32 connections are show below: RST -> Vdd (with pull-up resistor) IRQ -> Vtst (8.35V) Vdda, Vdd, Vddad -> Vdd (5V) CGMXFC -> GND PTA7, PTC1, PTC3 -> GND Vss, Vssad, Vssa -> GND PTC0 -> Vdd I think that are everything all right, but PROG08SZ always showns this error: Attempting half baud reset of HC08 device ... Unsuccessful Trying Security $FFFFFFFFFFFFFFFF (Failure of 68HC08 to respond properly. Check connections)
Please tell me that I do wrong? I thank very much in advance for your help.
PS. Please forgive my English, but I have still learnt it.
