(Power-down Mode) is measured with:
XTAL1=V
SS
; XTAL2=not connected; RESET=V
CC
; Port 0 =V
CC
; all other pins are disconnected. PLD not in Turbo Mode.
2. I

4. PLD is in non-Turbo Mode and none of the inputs are switching.
5. See Figure 72 for the PLD current calculation.
6. I/O current = 0 mA, all I/O pins are disconnected.
