2.2.4 Interrupt Controller
A total of 16 external interrupt lines (8 normal interrupt pins, 8 interrupt pins shared with
peripheral inputs for Wake Up from STOP mode, i.e. CAN RX and I
2C SDA)
Interrupts from internal peripherals (128 interrupt vectors)
Priority levels programmable for normal interrupt lines excluding the non-maskable one (16
levels)
Capable of using the normal interrupt pins for Wake Up from STOP mode
2.2.5 Internal Data RAM
24 KBytes integrated
Zero wait state for read/write access
2.2.6 Internal Program/Data RAM
16 kBytes integrated
Zero wait state for read/write access of instructions
One wait state for read/write access of data
2.2.7 External Bus Interface
If the mode pin MD_3 is set to “1”an external bus interface will become available instead of
several resources.
The external bus interface will include 16 data lines, 22 address lines, two chip select lines,
CLK, RDY, RDX, WRX0 and WRX1.
********** Limitation ***************************************************************************************
In MB91F467BA/466BA/465BA/464BA, you can not use Pin44 as general purpose port
in a state of
“MD_3 = 1”. It means that Pin44 is able to use only as “WRX1”.
(For a description of I/O Ports please refer to Hardware Manual chapter 55.)
