Problems after update from c166 v5.00 to c166 v5.05 (v6.02)

Hello all,

I have just updated from c166 v5.00 to v5.05 but the generated assembler code differs and the program is running errorious. I'm using an XC161CJ.


the instruction:

#define CC1_IOC_STAG ((T_Reg16 *) 0xF062)->bit2 // from Keil main.h

CC1_IOC_STAG = 1;


v5.00 generates:

00B8 D7400300 EXTP #03H,#01H
00BC F2F46230 MOV R4,03062H
00C0 7844 OR R4,#04H
00C2 D7500300 EXTP #03H,#01H
00C6 F6F46230 MOV 03062H,R4

works fine in the emulator and the real hardware


v5.05 (v6.02) generates:

00AA D190 EXTR #01H
00AC 2F31 BSET __Bit?F062?02

doesn't work on emulator and real target hardware. the emulator shows:

D190 EXTR #1
2F31 BSET 0FD62H.2


Anyone an Idea ? The adress 0xF062 in v5.05 is correct but the XC161CJ is obviously executing something else. I can't get whats the reason. any suggestions ?

best regards,
marcus
