| - | Set the audiogram data in the scratch memory: | + | Set the audiogram data in the scratch memory. 10 frequencies are stored in 50 bits, representing each value as a 5 bit number. The value stored is the hearing threshold divided by 5. This is rounded to the nearest 5, so 26 becomes 5 and 48 becomes 10. The minimum stored value is 0, the maximum stored value is 150. |
