Preliminary Data Sheet
• External voltage should not be applied to the chip I/O balls before the associated I/O power supply voltage is
• A chip power-down cycle must complete (all I/O supply voltages and VDD are below +0.4V) before a new
• During a power-up cycle, SysReset and TRST inputs should be asserted low. SysReset and TRST should
1. Measured at T
