Every 30ms an isolated port with address 0Ah is read data. If bits 2 and 5 are 1 and 0 respectively in memory mapped port at address F00Ah is sent read data divided by 2, otherwise the read data is sent multiplied by 7. The frequency of the oscillator crystal is 5MHz.
If bit 2,5==1,0 If bit 2,5==1,0 If bit 2,5==1,0 F00Ah Data/2 Else F00Ah Data*7
