The formula to find the priority number (P) is to divide by 4:
0xc = 12 (Dec) => Priority 3
Priority DecID HexID
1 4d 0x4
2 8d 0x8
3 12d 0xc
4 16d 0x10
5 20d 0x14
6 24d 0x18
Normally in SAE J1939, only priority 3 and 6 are used.
Hereafter the data can be read (PGN 61444):
0xcf00400 xD ff 7d 7d e0 15 ff f0 ff
Engine torque (Data byte 1) ff Not available
Driver demand torque (Data byte 2) 7d
Actual engine torque (Data byte 3) 7d
Engine speed (Data byte 4) e0
Engine speed (Data byte 5) 15
Source address (Data byte 6) ff Not available

Engine Demand (Data byte 8) ff Not available
Calculation example:
RPM resolution is 0.125 RPM/bit, offset 0.
The result is then 15e0 (Hex) or 5600 (dec)*0.125 = 700 RPM.
