ist the registers and bit values involved in setting up the following configurations Example: P1.4 to be an input with pull-down resistor P1SEL0 =0 in bit 4 P1SEL1 =0 in bit 4 P1DIR =0 in bit 4 P1REN =1 in bit 4 P10UT =0 in bit 4 P4.2 to be an output with extra strength P2.0 to be an input without resistor enabled P6.4 to be an input with pull-up resistor how C code to implement the three settings of the previous problem P4.2 to be an output with extra strength P2.0 to be an input without resistor enable P6.4 to be an input with pull-up resistor
