Show me what the menu will look like on the PC terminal program Puty. Explain the Interrupt Service Routine case statement. What does the main program loop do?

***CODE***

#include "config.h" #include "serial_uart.h" // Insert subroutines // Subroutine that transmits the Menu to the PC void Build_Menu() { putch(0x0c); printf(" \tMain Menu "); printf("\tf\tFirst Name "); printf("\tl\tLast Name "); printf("\t4\tToggle LED on RA4 "); printf("\t5\tToggle LED on RA5 "); printf("\t6\tToggle LED on RA6 "); printf("\tm\tMenu "); } // Interrupt Service Routine (ISR)) void interrupt my_isr(void) { int8_t c; if( RCIE && RCIF) { // Get character c = getch(); // Check what character was received and act on it switch(c) { case 'f': printf("First "); break; case 'l': printf("Last "); break; case 'm': Build_Menu(); break; case '4': if(LATAbits.LATA4 == 1) PORTAbits.RA4 = 0; else PORTAbits.RA4 = 1; break; case '5': if(LATAbits.LATA5 == 1) PORTAbits.RA5 = 0; else PORTAbits.RA5 = 1; break; case '6': if(LATAbits.LATA6 == 1) PORTAbits.RA6 = 0; else PORTAbits.RA6 = 1; break; } } } // Main program int main(int argc, char** argv) { // Local variables int cnt; // Setup the oscillator OSCILLATOR_Initialize(); // Initialize PPS and PORTS PORT_PIN_Initialize(); // Initialize the UART UART_Initialize(); // Draw the menu Build_Menu(); while (1) { } }
