The number of bytes a 1 Mbit/s SPI link transfers in 1 ms is about
Answer: C
Correct answer: 125
\[ 1{,}000{,}000\ \mathrm{bits/s} \times 0.001\ \mathrm{s} = 1000\ \mathrm{bits} = 125\ \mathrm{bytes}. \] SPI has no framing overhead, so the division is simply by eight - unlike the UART calculation above, where the start and stop bits make it ten. Forgetting to convert bits to bytes gives the 1000 offered here.
