Output signals (read mode)
The interrupt flag will be cleared when this register is read. To prepare for a new interrupt, a
“1” must be re-written in the IT enable bit (Reg. 04, d7).
Power-on reset — bus register initial conditions
Power-on reset is active when the supply V
Non-significant bits (X) are pre-set to “0”
