WatchDog
32 bits watchdog counter width
Counter clock is from apb bus clock
Counter counts down from a preset value to 0 to indicate the occurrence of a timeout
WDT can perform two types of operations when timeout occurs:
Generate a system reset
First generate an interrupt and if this is not cleared by the service routine by the
time a second timeout occurs then generate a system reset
Programmable reset pulse length
Totally 16 defined-ranges of main timeout period
Interrupt Controller
Support 3 PPI interrupt source and 112 SPI interrupt sources input from different
components inside RK3288
Support 16 softwre-triggered interrupts
Input interrupt level is fixed , only high-level sensitive
Two interrupt outputs (nFIQ and nIRQ) separatelyfor each Cortex-A17, both are
low-level sensitive
Support different interrupt priority for each interrupt source, and they are always
software-programmable
DMAC
Micro-code programming based DMA
The specific instruction set provides flexibility for programming DMA transfers
Linked list DMA function is supported to complete scatter-gather transfer
Support internal instruction cache
Embedded DMA manager thread
Support data transfer types with memory-to-memory, memory-to-peripheral,
peripheral-to-memory
Signals the occurrence of various DMA events using the interrupt output signals
Mapping relationship between each channel and different interrupt outputs is
software-programmable
Two embedded DMA controller , BUS_DMAC is for bus system, PERI_DMAC is for
peripheral system
BUS_DMAC features:
6 channels totally
6 hardware request from peripherals
2 interrupt output
Dual APB slave interface for register config, designated as secure and non-secure
Support trustzone technology and programmable secure state for each DMA
channel
PERI_DMAC features:
7 channels totally
9 hardware request from peripherals
2 interrupt output
Not support trustzone technology
Security system
Support trustzone technology for the following components inside RK3288
Cortex-A17, support security and non-security mode, switch by software
BUS_DMAC, support some dedicated channels work only in security mode
eFuse, only accessed by Cortex-A17 in security mode
Internal memory , part of space is addressed only in security mode, detailed size
is software-programmable together with TZMA(trustzone memory adapter) and
TZPC(trustzone protection controller)
Embedded encryption and decryption engine
