Can`t understand the calculations.
There is following In documentation (UM10562 chapter 37.5.1.5):
... Programming a zero will result in a one cycle wait state.
PHASE3 = ( 15ns * cclk) - 1 = (15ns * 120MHz) - 1 = 1.8
Therefore, PHASE3 = 2
...
Table 725. EEPROM wait state register (WSTATE - address 0x0020 0090) bit description
7:0 PHASE3 Wait states 3 (minus 1 encoded).
The number of system clock periods required to give a minimum time of 15 ns.
But when i calculate:
(15 * 0.120) - 1 = 1.8 - 1 = 0.8
then round to nearest bigger integer = 1
What have i missed? Should i decrement or not?
