MB90480/485 Series

(3) Port Input Resistance Registers
These registers control the use of pull-up resistance in input mode.
0 : No pull-up resistance in input mode.
1 : With pull-up resistance in input mode.
In output mode, these registers have no significance (no pull-up resistance) . Input/output mode settings are
controlled by the port direction (DDR) registers.
In case of a stop (SPL
= 1) , no pull-up resistance is applied (high impedance) . This function is prohibited when
an external bus is used. Do not write to these registers.
(4) Port Output Pin Registers
*1 : The value is set to “
” on MB90485 series only.
*2 : The initial value of this bit is “XX000000B” on MB90485 series only.
These registers control open drain settings in output mode.
0 : Standard output port functions in output mode.
1 : Open drain output port in output mode.
In input mode these registers have no significance (Hi-Z output) . Input/output mode settings are controlled by
direction (DDR) registers. This function is prohibited when an exteral bus is used. Do not write to these registers.
(5) Analog Input Enable Register
This resister controls the port 6 pins as follows.
0 : Port input/output mode.
1 : Analog input mode. The default value at reset is all “1”.
(6) Up-down Timer Input Enable Register
This register controls the port 3 pins as follows.
0 : Port input mode.
1 : Up/down timer input mode.The default value at reset is “0”.
The MB90480/485 series uses the following setting values : UDE0 : P30/AIN0, UDE1 : P31/BIN0/UDE2 : P32/
ZIN0,
UDE3 : P33/AIN1, UDE4 : P34/BIN1, UDE5 : P35/
