4.3.1.5 Program Branching Instructions
The 8051 supports a set of conditional and unconditional jump instructions that help to modify the program execution flow.
shows the list of jump instructions.

4.4 DMA and PHUB
The PHUB and the DMA controller are responsible for data
transfer between the CPU and peripherals, and also data
transfers between peripherals. The PHUB and DMA also control
device configuration during boot. The PHUB consists of:
There are two PHUB masters: the CPU and the DMA controller.
Both masters may initiate transactions on the bus. The DMA
channels can handle peripheral communication without CPU
intervention. The arbiter in the central hub determines which
DMA channel is the highest priority if there are multiple requests.
