#55534 - RE: troubles moving from AT89C52 to AT89S52
Responding to: ???'s previous message
Hi,
Are you by any chance using ALE pin for some special puppose...?thats because the AUXR register by default in the AT89Sxx series are reset to 0x00,so the ALE always emits 1/6 the oscillator frequency...

Can you give more details



DISALE Disable/Enable ALE
DISALE Operating Mode
0 ALE is emitted at a constant rate of 1/6 the oscillator frequency
1 ALE is active only during a MOVX or MOVC instruction
