1 The external port protocols employ bus IDLE cycles for bus mastership transitions as well as slave address boundary crossings to avoid any potential bus contention. The
apparent driver overlap, due to output disables being larger than output enables, is not actual.
2 For input specifications on FLAG3–0 pins, see Table 21.
3 These input pins are asynchronous and therefore do not need to be synchronized to a clock reference.
4 For additional requirement details, see Reset and Booting on Page 9.
5 RST_IN clock reference is the falling edge of SCLK.
6 TDO output clock reference is the falling edge of TCK.
7 Reference clock depends on function.
8 These pins may change only during reset; recommend connecting it to V
DD_IO/VSS.
9 STRAP pins include: BMS, BM, BUSLOCK, TMR0E, L1BCMPO, TM2, and TM3.
10Specifications applicable during reset only.
