I may have asked this question some time ago> i tried to check did not find anything so here it goes. How to evaluate this operation:
PCA0MD &= ~0x40; PCA0MD is a register for a processor....

it's for an embedded microcontroller to interface w/ an LCD. When the LCD is powered on it takes 10ms to initialize where no instructions can be written. Durring this time the Line D7 is high then...

How would i determine how long it takes to complete an instruction?

for the below function i can pass an unsigned char "count" so i can adjust the delay ….so lets say I pass 1 how long would it...

1.​​​It seems like at least for writting code for microcontroller eval boards that unlike assembler C does not do well with just listing rows and rows of code in "main.c" Seems like functions are the...

so would it be a bitwise AND 1's complement then NOT?

so the first part & is a bitwise of 0x40 01000000 so would the first operand 0x40 be bitwised with the second operand of zeros? that would result in all zeros, then it would be bitwise not? the...

so PCAOMD is a register on a micro processor. so usually they have an 8 bit register that you can turn a function on or off by binary code so if it was just PCA0MD = 0x40 that would be 01000000 so...
