5.18 Flash Interface Timing Requirements

The DLPC23x-Q1 ASIC flash memory interface consists of an SPI serial interface. See Section 7.3.4.

(1) The DLPC23x-Q1 communicates with flash devices using a slight variant of SPI Transfer Mode 0 (that is, clock polarity = 0, clock phase = 0). Instead of capturing MISO data on the clock edge opposite from that used to transmit MOSI data, the DLPC23x-Q1 captures MISO data on the same clock edge used to transmit the next MOSI data. As such, the DLPC23x-Q1 Flash SPI interface requires that MISO data from the flash device remain active until the end of the full clock cycle to allow the last data bit to be captured. This is shown in Figure 5-8.
(2) The actual maximum clock rate driven from the DLPC23x-Q1 can be slightly less than this value.
