JUMP instruction of nedoRISC Core:
| 23 | 22 | 21 | 20 | 19 | 18 | 17 | 16 | 15 | 14 | 13 | 12 | 11 | 10 | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
| 0 | 0 | 0 | 1 | 20-bit address of new program counter |
In user mode after this instruction register r15 gets lower 16 bits of new address and 4-bit field PCHI of flags register r14 gets higher nibble of new address.
If higher 10 bits are all zeros then processor will switch to Supervisor? mode.
