The value of P01.05 is 100000 (32-bit parameter of type I, 0x000186A0);
The value of P01.06 is -100000 (32-bit parameter of type I, 0x FFFE7960);
The value of P01.07 is 0x FFFF (16-bit parameter of type II).
The values returned in the reading operation are as shown in the following table:
Register
address
Access mode Value returned Description
P01.01
16-bit 0x1194 The actual value is returned.
32-bit 0x00001194
The 16 high bits are filled with 0 and the actual value
is returned.
P01.02
16-bit 0xFE0C
The 16 low bits are captured and the value retuned is
-500, which is different from the actual value.
32-bit 0x0000FE0C The actual value is returned.
P01.03
16-bit 0xFE0C The actual value is returned.
32-bit 0xFFFFFE0C
The 16 high bits are filled with 1 and the actual value
is returned.
P01.04
16-bit 0x1388
The 16 low bits are captured and the actual value is
retuned.
32-bit 0x00001388 The actual value is returned.
P01.05
16-bit 0x86A0
The 16 low bits are captured and the value retuned is
-31072, which is different from the actual value.
32-bit
0x000186A0
The actual value is returned.
P01.06
16-bit 0x 7960
The 16 low bits are captured and the value retuned is
31072, which is different from the actual value.
32-bit 0x FFFE7960 The actual value is returned.
P01.07
16-bit 0x FFFF
32-bit 0x0000FFFF Parameter of type II, the 16 high bits are filled with 0.
As shown in the above table, when reading the parameter with an actual length of 32 bits in the 16-bit mode,
the value returned may not be equal to the actual value. Therefore, please note: the reading operation of the
16-bit mode is only applicable to parameters with the current value range from -32768 to 32767, and the
reading operation of other parameters shall adopt the 32-bit mode.
2. Writing operation
(1) Command codes 0x06 and 0x41
Both of these command codes supports changing the single parameter of 16 bits and do not support the 32-bit
access mode. If the highest bit of the start register address in the request frame is 1, it will return to the
abnormal information frame, indicating that the address is wrong.
