The clock input to the 16-bit up counter in the PCA block

is user-programmable.

I need it for calculate the time of the period.

fPCA0CLK = fOSC / (2 ^ PCA0PS[3:0])

Divisor range: 1, 2, 4, 8, 16... 16384, 32768

I don't understand how can I get the divisor range up to 7?

Due to the fact that I have only 3 bits in the prescaler PCA0PS[3:0].

Thank you,
