#134403 - Which manual are you referring? Responding to: ???'s previous message |
pl ref pg 87,88 ,100, 101 & 113 of manual Which manual are you referring? See this manual from SanDisk instead. "SanDisk MultiMediaCard and Reduced-Size MultiMediaCard, ver1.3" http://www.sandisk.com/Assets/Fi...MCv1.3.pdf (1) Can clock be stopped? what is requirment of minimum 8 clock cycles after command or data response packet.
(2) It is a minimu 8 clock cycle so more no of clock cycle can also be given? then how SC/MMC card will know that these clock cycle are not for clocking in next instrcuction ? See "5.12 Clock Control" (p5-8) This section describes how to shut down SPI SCK, and In which case the eight clock are required before shutting it down. (3) Nac period (Read wait tiem after read command) should be clock running during this period ? Do you mean NAC period on single block/multiple read timing? Then, yes. SPI has to be driven as described in this section. 5.23 SPI Bus Timing Diagrams (p5-18) To realize this diagram correctly, please note this symbol. " * - Repeater" ie. "H *******" means "H HHHHHHH" - The line is held to H within this period. Tsuneo |
