 		 #69388 - RE: PROBLEM FROM 8051RD2 TO AT89C51RD2
Responding to: ???'s previous message
I don't know whether this is the same for the Temic part, but:

These (AT89C51RD2) parts start up in ISP mode by default. You need to check that your programmer is setting all the 'special' bytes to the correct values after programming the device.

A quick test you could perform to see whether the thing is in ISP mode is to transmit a 'U' to the UART. Use 9600,8,n,2. If it responds with a 'U' it is in ISP mode.
