The Microchip TC77 is a small-footprint digital temperature sensor with a 13-bit resolution. This device uses a single pin for temperature I/O, which one would need to use the SPI bidirectional mode to read the temperature. The data sheet of this device is included in the complementary CD (it can also be downloaded from the Microchip website, https://www.microchip.com). Describe the circuit connection of this chip and the HCS12. Write a program to configure the TC77 to continuous conversion mode, read the temperature once every second, and display the temperature on the LCD. The block diagram and the pin assignment of the TC77 are shown in Figure E10.8.
