38 / 98 page S26KL512S / S26KS512S S26KL256S / S26KS256S S26KL128S / S26KS128S Document Number: 001-99198 Rev. *F Page 38 of 98 Table 18. Drive Strength Code Note: 1. Typical Impedance measured at nominal VCCQ, 25°C. Figure 17. Configuration Control Notes: 1. A Software Reset will not change the state of the CR Select Multiplexer. 2. Programming or erasure of the NVCR does not impact the contents of the VCR that has been previously loaded. 3. If the VCR has not been loaded, programming of the NVCR will be result in the VCR being loaded with the new NVCR value. . Notes: 1. Programming / Erasing the NVCR will not impact behavior until after the next POR or Hardware Reset. 2. Loading the VCR will impact behavior immediately. 3. This state occurs after NVCR[11] = VCR[11] = 1 and the NVCR[11] bit is programmed. The state will only exist until the next POR or Hardware Reset. Thereafter NVCR[11] = VCR[11] = 0. 4. This state occurs after POR or Hardware Reset when NVCR[11] was previously programmed. xVCR14 – xVCR12 Typical Impedance 1.8V VCCQ Typical Impedance 3V VCCQUnits 000 (default) 27 20 Ohms 001 117 71 010 68 40 011 45 27 100 34 20 101 27 16 110 24 14 111 20 12 CR Select Multiplexer DIR=0=NVCR DIR=1=VCR Volatile Configuration Register Non-Volatile Configuration Register Device Configuration Set Clear Clear Load Volatile Configuration Register Power-On Reset Hardware Reset DIR Table 19.
