Notes
1. When using pins 33–34 on header J3 to drive LEDs, these pins can handle a sinking
current of up to 8 mA.
2. The VRAM voltage is temperature-dependent. If the VRAM voltage drops below about
1.2 V to 1.5 V, the contents of the battery-backed SRAM may be lost. If VRAM drops
below 1.0 V, the 32 kHz oscillator could stop running. Pay careful attention to this volt-
age if you draw any current from this pin.
