The second line, LATB.B1 = 1; will be decoded like in this way:

READ LATB is read: STORE Since the voltage levels on MCU pins are no

longer relevant, we get the expected value:

Actual voltage levels on MCU pins are no longer relevant when using LATx for output

MODIFY Data is modied to set the bit:

WRITE LATB is written with the new data. The

output driver for RB1 turns on, and the output

driver for RB0 remains turned on:

When to use LATx instead of PORTx

Depending on your hardware, one may experience unpredictable behavior when using PORTx bits for driving output.

Displays (GLCD, LCD), chip select pins in SPI interfaces and other cases when you need fast and reliable output, LATx

should be used instead of PORTx.
