= Should be set to High (1) to operate the APD.
Bit 1
0 = ALE Power Down (PD) Polarity Low.
1 = ALE Power Down (PD) Polarity High.
Bit 2
0 = Automatic Power Down (APD) Disable.
1 = Automatic Power Down (APD) Enable.
Bit 3
0 = EPROM/SRAM CMiser is OFF.
1 = EPROM/SRAM CMiser is ON.
Bit 4
0 = ZPLD Turbo is ON. ZPLD is always ON.
1 = ZPLD Turbo is OFF. ZPLD will Power Down when inputs are not changing.
Bit 5
0 = ZPLD Clock Input into the Array from the CLKIN pin input is connected.
Every Clock change will Power Up the ZPLD when Turbo bit is OFF.
1 = ZPLD Clock Input into the Array from the CLKIN pin input is disconnected.
Bit 6
0 = ZPLD Clock Input into the the MacroCell registers from the CLKIN pin input
is connected.
1 = ZPLD Clock Input into the the MacroCell registers from the CLKIN pin input
is disconnected.
Bit 7
*
= In the PSD4XX should be set to High (1)
Bit 0
0 = Automatic Power Down Unit Clock is connected to Port E7 (PE7) alternate
function input.
1 = Automatic Power Down Unit Clock is connected to the PSD Clock
input (CLKIN).
0 = Sleep Mode Disabled.
1 = Sleep Mode Enabled.
