sage. The DNT24 event timer triggers sending the stored command to the DNT24’s slave. The stored command can be
up to 16 bytes in length. Figure 3.2.1 shows the required SPI master mode-signal connections, and Figure 3.2.2 shows
the SPI master-mode timing.

In SPI slave mode, the host can stream data into DNT24 at up to 250 kbps, provided the host suspends clocking within 10
bytes following a low-to-high transition on /HOST_CTS. The host can clock data into the DNT24 at up to 4 Mbps for data
bursts of up to 50 bytes, provided the interval from the end of one burst to the start of the next burst is at least 2 ms, and
the host suspends clocking on a low-to-high transition on /HOST_CTS. See Figure 3.2.4
