NOTES:
1. All read and write operations must have ceased a minimum of 4 WCLK and 4 RCLK cycles before power down is asserted.
2. When the PD input becomes deasserted, there will be a 1µs waiting period before read and write operations can resume.
3. Set-up and configuration static inputs are not affected during power down.
4. Serial programming and JTAG programming port are inactive during power down.
5. RCS = 0, WCS = 0 and OE = 0. These signals can toggle during and after power down.
6. All flags remain active and maintain their current states.
7. During power down, all outputs will be in high-impedance.
