(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
