		Table 8. DMA Test Patterns
	Test Pattern		Description
	"16 00's 16 FF's"		Full the entire host DMA buffer with 16
			bytes of 00’s and then 16 bytes of FF’s.
	"16 FF's 16 0's"		Full the entire host DMA buffer with 16
			bytes of FF’s and then 16 bytes of 00’s.
	"32 00's 32 FF's"		Full the entire host DMA buffer with 32
			bytes of 00’s and then 32 bytes of FF’s.
	"32 FF's 32 00's"		Full the entire host DMA buffer with 32
			bytes of FF’s and then 32 bytes of 00’s.
	"00000000's"		Full the entire host DMA buffer with all
			zeros.
	"FFFFFFFF's"		Full the entire host DMA buffer with all
			FF’s.
	"AA55AA55's"		Full the entire host DMA buffer with data
			0xAA55AA55.
	"55AA55AA's"		Full the entire host DMA buffer with data
			0xAA55AA55.
Default: Enabled

B6. External SRAM Test

Function: It tests DMA SRAM by performing the tests described in test B1. The Scratch Pad Test.

Default: Disabled

C1. EEPROM Test

Function: An increment test data is used in EEPROM test. It fills the test data into the test range and read back to verity the content. After the test, it fills data with zero to clear the memory.

Default: Enabled

C2. CPU Test

Function: This test opens the file cpu.bin. If file exists and content is good, it loads code to rx and tx CPU and verifies CPU execution.

Default: Enabled
