TEST 0 REGISTER (Address 0Dh)
The Test Pattern Select bits determine which test pattern is output when the Test Pattern Generator (TPG)
mode or the Built-in Self-Test (BIST) mode is enabled. Table 5 gives the codes corresponding to the various test
patterns. All HD colour bar test patterns are inherently BIST data. BIST test patterns for SD are: NTSC, 27MHz,
4x3 Colour Bars and PAL, 27MHz, 4x3 PLL Pathological.
The TPG Enable bit when set to a logic-1 enables the Test Pattern Generator function and built-in self-test
(BIST).
The Pass/Fail bit indicates the result of the built-in self-test. This bit is a logic-1 for a pass condition.
