Answer 1

The maximum clock speed of the TM4C123G CPU is 80 MHz. It has 43 I/O pins and various types of memory, including Flash Memory, SRAM, and EEPROM. Each General Purpose I/O Port or Pin has special/alternative functions.

Step-by-step explanation:

(a) The maximum clock speed of the CPU of TM4C123G is 80 MHz.

(b) The TM4C123G microcontroller has a total of 43 I/O pins.

(c) The memory available in TM4C123G microcontroller includes:

• Flash Memory: With a size of 256 KB or 512 KB, it is used for storing program instructions.
• SRAM: With a size of 32 KB, it is used for storing data that is needed for the program execution.
• EEPROM: With a size of 2 KB, it is used for non-volatile data storage.

(d) The special/alternative functions for each General Purpose I/O Port or Pin are as follows:

1. Port A, pin 0: ADC0 (Analog-to-Digital Converter 0).
2. Port B, pin 3: SSI1FSS (Serial Synchronous Interface 1 Frame Slave Select).
3. Port D, pin 5: U1CTS (UART1 Clear To Send).
4. Port E, pin 2: SSI0CLK (Serial Synchronous Interface 0 Clock).
