Interrupt registers: 0x02, 0x03, 0x04

The registers 0x02, 0x03 and 0x04 are used for the interrupt management and in particular:

0x02: interrupt status (reset value 0x00), bit at 0 means “no interrupt”

0x03: interrupt latch (reset value 0x00), bit at 0 means “not latched”

0x04: interrupt mask (reset value 0x0E), bit at 0 means “not masked”

The single bits are organized as follows:
