Our C code is like:
SIM->SCGCS & -(mask); // clear all bits of interests (bit 10 and 12)
SIM->SCGCS |- value; // Set bits of interests to target value
What should be the value to enable the clock of PORT B and D on the Freedom board to allow the
RGB LED to interface with KL-25Z device?
Mask = Ox00001400 and Value Ox00001400
O No answer text provided.

Question 2
Is the following C code equivalent to each other if they run on the KL-25Z device? Assume the
mask and value are
Mask in hex =
Ox00001400
Value in hex = Ox00001400
Code 1:
SIM->SCGC5 &= -(mask);
SIM->SCGC5 |- value;
Code 2:
SIM->SCGC5 |- SIM_SCGC5_PORTB_MASK & SIM_SCGC5 PORTD_MASK;
O True
O False
