Intrоductiоn tо Questions 3-8 Imаge thаt in а COVID-like affected semester of this course (when the labs were all remote), a student assembled most of the given lab kit without supervision, although the student was probably not sufficiently prepared to do so. While soldering some components, the student somehow let the soldering iron rest directly on the µPAD. In doing so, the student end up destroying the internal DAC system of the ATxmega128A1U, but this remained unknown to the student. Later on in the semester, the student finally realized this terrible mistake. Although the student is ultimately given the option to pay for a replacement µPAD, you decide (with permission from Dr. Schwartz) to help the student as follows: you employ your knowledge acquired previously from 4744 and attempt to connect an external DAC system to the student's microcontroller. (Throughout Questions 3-8 of this exam, you will solve some design problems related to connecting an external DAC system to the microcontroller.) ———————————————————————————————————— After conducting some appropriate research, you select an external DAC system and determine the following: [1] The DAC has one channel of 6-bit resolution. [2] The DAC must be configured via the SPI protocol, and it is only possible to write to the device. In particular, the device expects the SPI write protocol depicted in Fig. 1, where "D",
