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.

4.4.2 DMA Features
PHUB Spokes
24 DMA channels
Each channel has one or more transaction descriptors (TD) to
configure channel behavior. Up to 128 total TDs can be defined
TDs can be dynamically updated
Eight levels of priority per channel
Any digitally routable signal, the CPU, or another DMA channel,
can trigger a transaction
Each channel can generate up to two interrupts per transfer
Transactions can be stalled or canceled
Supports transaction size of infinite or 1 to 64 KB
TDs may be nested and/or chained for complex transactions
