ADUC816 ?2? rev. a.0 feb.?00 silicon - errata sheet # 816_01. indirect addressing mode- : background: in indirect addressing the instruction specifies a register which contains the address of the operand. both internal and external ram can be indirectly addressed. eg. mov a, @r0. issue: the following special function registers (sfrs) cannot be read using indirect addressing modes: adcmode, adc0con, adc1con, sf, icon, psmcon, adcstat, adc0l/m/h, adc1l/h, of0l/m/h, of1l/h, gn0l/m/h, gn1l/h, dacl/h, daccon. work-around : instead of executing the indirectly addressed read instruction as mov @ri, adcstat it should instead be executed as mov a, adcstat mov @ri, a related issues : reading, using indirect addressing, functions correctly for all sfrs other than those mentioned above. writing, using indirect addressing, functions correctly for all sfrs including those mentioned above.
