MB90470 Series

(3) Input Resistance Registers

These registers control pull-up resistance in input mode.

0 : No pull-up resistance in input mode.

1 : Pull-up resistance applied in input mode.

In output mode, the setting has no significance (no pull-up resistance) . The direction registers (DDR) control

switching between input and output modes.

In stop mode (SPL

= 1) pull-up resistance is removed (high impedance) . When an external bus is used, this

function is prohibited and no values should be written to this register.

(4) Output Pin Registers

These registers control open drain operation in output mode.

0 : Operates as standard output port in output mode.

1 : Operates as open drain port in output mode.

In input mode, the setting has no significance (High-Z output) . The direction registers (DDR) control switching

between input and output modes. When an external bus is used, this function is prohibited and no values should

be written to this register.

(5) Analog Input Enable Register

This register controls the port 6 pins as follows.

0 : Port input/output mode.

1 : Analog input mode.

The register value is “1” at reset.

(6) Up-down Timer Input Enable Mode

This register controls the port 3 pins as follows.

0 : Port input mode

1 : Up-down timer input mode.

The register value is “0” at reset.

In the MB90470 series, the pin functions are as follows : UDE0 : P30/AIN0, UDE1 : P31/BIN0, UDE2 : P32/

ZIN0, UDE3 : P33/AIN1, UDE4 : P34/BIN1, UDE5 : P35/ZIN1
