MB90330 Series
36
Register list (Analog input enable register)
This register controls the port 7, 8 pins as follows.
0 : Port input/output mode.
1 : Analog input mode.
This bit becomes 1 after a reset.
Register list (Port pull-up resistance register)
Controls the pull-up resistor in input mode.
0 : Without pull-up resistor in input mode.
1 : With pull-up resistor in input mode.
Meaningless in output mode. (Without pull-up resistor)/The input/output mode is decided by the setting of the
port direction register (DDR).
Without pull-up resistor is used in stop mode (SPL = 1). (High-Z) This function is disabled when the external
bus is used. Do not attempt to write to this register.
Register list (Output pin register)
Controls open-drain in output mode.
0 : Serves as a standard output port in output mode.
1 : Serves as an open-drain output port in output mode.
Meaningless in input mode (output High-Z)./The input/output mode is decided by the setting of the port direction
register (DDR). This function is disabled when the external bus is used. Do not attempt to write to this register.
