269 / 393 page  269 8018N–AVR–08/09 ATmega169P HOLD Input Sample & Hold signal. Sample analog signal when low. Hold signal when high. If differential amplifier is used, this signal must go active when ACLK is high. 11 IREFEN Input Enables Band-gap reference as AREF signal to DAC 00 MUXEN_7 Input Input Mux bit 7 0 0 MUXEN_6 Input Input Mux bit 6 0 0 MUXEN_5 Input Input Mux bit 5 0 0 MUXEN_4 Input Input Mux bit 4 0 0 MUXEN_3 Input Input Mux bit 3 0 0 MUXEN_2 Input Input Mux bit 2 0 0 MUXEN_1 Input Input Mux bit 1 0 0 MUXEN_0 Input Input Mux bit 0 1 1 NEGSEL_2 Input Input Mux for negative input for differential signal, bit 2 00 NEGSEL_1 Input Input Mux for negative input for differential signal, bit 1 00 NEGSEL_0 Input Input Mux for negative input for differential signal, bit 0 00 PASSEN Input Enable pass-gate of differential amplifier. 11 PRECH Input Precharge output latch of comparator. (Active low) 11 SCTEST Input Switch-cap TEST enable. Output from differential amplifier is sent out to Port Pin having ADC_4 00 ST Input Output of differential amplifier will settle faster if this signal is high first two ACLK periods after AMPEN goes high. 00 VCCREN Input Selects Vcc as the ACC reference voltage. 00 Table 25-3. Boundary-scan Signals for the ADC (1) (Continued) Signal Name Direction as Seen from the ADC Description Recommen- ded Input when not in Use Output Values when Recommended Inputs are Used, and CPU is not Using the ADC |
