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
For input specifications on FLAG3–0 pins, see
These input pins are asynchronous and therefore do not need to be synchronized to a clock reference.
For additional requirement details, see
RST_IN clock reference is the falling edge of SCLK.
TDO output clock reference is the falling edge of TCK.
Reference clock depends on function.
These pins may change only during reset; recommend connecting it to V
STRAP pins include: BMS, BM, BUSLOCK, TMR0E, L1BCMPO, L2BCMPO, and L3BCMPO.
Specifications applicable during reset only.
