Port 2 register
The port2 register contains the port 2 data register (PDR2) , the port 2 direction register (DDR2) and the high
address control register (HACR).
The high address control register (HACR) enables or disables the output of external addresses (A16 to A23).
When the register enables the output of the external addresses, the port can not be used as a peripheral
device and a general-purpose I/O port.
The bits making up the register are in a one-to-one relationship with the port 2 pins.
Port 2 Register and Corresponding Pins
Port 3 register
The port3 register contains the port 3 data register (PDR3) and the port 3 direction register (DDR3) .
The bus control signal selection register (ECSR) enables or disables the input and output of external bus
control signals (WRL / WRH, HRQ / HAK, RDY, CLK). When the register enables the input and output of the
external bus control signals, the port can not be used as a peripheral device and a general-purpose I/O port.
The bits making up the register are in a one-to-one relationship with the port 3 pins.
Port 3 Register and Corresponding Pins
Port 4 register
The port4 register contains the port 4 data register (PDR4) and the port 4 direction register (DDR4) .
The bits making up the register are in a one-to-one relationship with the port 4 pins.
