Writing a 1 to CLR_INT (Table 22) clears all the event
registers and the corresponding interrupt bits in register
R00h. Writing a 1 to RESET_P_ turns off power to the cor-
responding port and resets only the status and event

A logic high softly resets port 2
A logic high softly resets port 1
registers of that port. After execution, the bits reset to 0.
Writing a 1 to RESET_IC causes a global software reset,
after which the register map is set back to its reset state.
A reset sets R1Ah = 00h.
