A write to a PORTB
register writes to the corresponding LATB register (PORTB data latch). Those I/O port
pin(s) configured as outputs are updated. A write to a PORTB register is effectively the
same as a write to a LATB register. A read from a PORTB register reads the synchronized
signal applied to the port I/O pins.
