57 / 89 page  57/89 PSD834F2V 2. Typical current consumption assuming no PLD inputs are changing state and the PLD Turbo bit is 0. For Users of the HC11 (or compatible). The HC11 turns off its E clock when it sleeps. There- fore, if you are using an HC11 (or compatible) in your design, and you wish to use the Power-down mode, you must not connect the E clock to CLKIN (PD1). You should instead connect a crystal oscil- lator to CLKIN (PD1). The crystal oscillator fre- quency must be less than 15 times the frequency of AS. The reason for this is that if the frequency is greater than 15 times the frequency of AS, the PSD keeps going into Power-down mode. Figure 30. Enable Power-down Flow Chart Other Power Saving Options. The PSD offers other reduced power saving options that are inde- pendent of the Power-down mode. Except for the SRAM Stand-by and PSD Chip Select Input (CSI, PD2) features, they are enabled by setting bits in PMMR0 and PMMR2. Enable APD Set PMMR0 Bit 1 = 1 PSD in Power Down Mode ALE/AS idle for 15 CLKIN clocks? RESET Yes No OPTIONAL Disable desired inputs to PLD by setting PMMR0 bits 4 and 5 and PMMR2 bits 2 through 6.
