48 / 62 page ![]() www.national.com 48 Revision 2.1 5.0 Electrical Specifications This section provides information on absolute maximum ratings, recommended operating conditions, DC character- istics, and AC characteristics. All voltage values in the Electrical Specifications are with respect to VSS unless oth- erwise noted. 5.1 TEST MODES The CS9211 can be forced into different test modes. Table 5-1 summarizes the test mode selection process. 5.1.1 NAND Tree Mode TheNAND treemodeisusedtotestinput andbi-direc- tional pins which will be part of the NAND tree chain. The NAND tree chain starts on pin 3 (UD11) and ends on pin 143 (MA2) where the output of the chain is captured. The following pins are not included in the NAND chain: — All supply pins — MBIST_EN (pin 45) — SCAN_EN (pin 46) — TEST_SE (pin 47) — XTALIN (pin 48) — XTALOUT (pin 49) Table 5-1. Test Mode Selection Mode SCAN_EN (Pin 46) TEST_SE (Pin 47) NAND tree test 01 Table 5-2.
