#ifdef MZ61581
// SPI_BUS_CLOCK_DIVISOR specifies how fast to communicate the SPI bus at. Possible values are 4, 6, 8, 10, 12, ... Smaller
// values are faster.
// The following bus speed have been tested on Tontec 3.5" display with marking "MZ61581-PI-EXT 2016.1.28" on the back (on a Pi 3B+):
// core_freq=280: CDIV=2, results in 140.00MHz, works
// core_freq=281: CDIV=2, results in 140.50MHz, works, but oddly there is a certain shade of brown color on the ground of OpenTyrian that then starts flickering faintly red - everything else seemed fine. (At 142.5MHz very noticeable)
