Notes:
1. During a system-initiated reset, Reset must be taken low for a minimum of 2048 SysClk cycles.
2. The BootW input has a maximum rise time requirement of 10 ns when it is tied to Reset.
3. Input hold times are measured at 3.47V and T = 0°C.

4. 403GCX-3JC80A and 403GCX-3BC80A with application relief applied meet all 40 MHz asynchronous input tim-
ings.
