Data formats
Accura 7500 supports the following data formats.
UINT16: 16bit unsigned integer
It is a register value ranging from 0 to 65535.
INT16: 16bit signed integer
It is a register value ranging from -32768 to 32767.
UINT32 or INT32
32 bits are divided into two consecutive 16-bit registers. The first and second registers are the upper
and lower registers. The formula for converting to 32bit data is as follows.
Register value = (Upper register x 65536) + lower register

UINT32 (Unsigned 32bit)
Both the upper and lower registers are unsigned 16bit integers.
Example) If upper register value = 0x10BF (unsinged) = 4287,
lower register value = 0x126F (unsinged) = 4719,
Register value = (4287 x 65536) + 4719 = 280957551

INT32 (Signed 32bit)
The upper register is a signed 16bit integer, and the lower register is an unsigned 16bit
integer.
Example) If upper register value = 0xFFFF (signed) = -1,
lower register value = 0x126F (unsinged) = 4719,
Register value = (-1 x 65536) + 4719 = - 60817
