• Description: V830TM 32-BIT MICROCONTROLLER
• Manufacturer: NEC [NEC]

9.1.1 Integers
Digit ordering for integers is as follows: Bit 0 is handled as the least significant bit, regardless of the data length.
Larger bit numbers correspond to higher orders.
9.1.2 Unsigned integers
a positive integer. Data of this data type is represented by a binary number and has a size of a byte, halfword, or
word. Digit ordering for unsigned integers is as follows: Bit 0 is handled as the least significant bit, regardless of the
data length. Larger bit numbers correspond to higher orders.
9.2 Data Alignment
boundaries for halfword data, and byte boundaries for byte data. If a data alignment error is detected, the data address
is automatically changed to an accessible address. It is impossible to predict whether this address change will lead
to correct or incorrect data access. This change is made as follows:
In the V830, integers are represented by twos complements. They are expressed by bytes, halfwords, or words.
Unsigned integers are of a data type for which the most significant bit is not handled as a sign bit, but all bits represent
The V830 requires that data be aligned with appropriate boundaries: word boundaries for word data, halfword
