Freescale Semiconductor
Direct Slave Interface (DSI)
14.2.2 Full Address Addressing Mode
In Full Address mode, the host can access the DSI with
HA[11–29]
as mandatory bits and
HA[7–10],
which can be enabled by the DCR[ADREN] control bits (see page 14-29). If only
HA[11–29]
uses
(DCR[ADREN] = 0b0000), then the external address space is accessed through a slot (window),
in the internal 2 MB address space (see Figure 14-3).
If at least one of the bits in the register field DCR[ADREN] has a value of 1, then the host uses
the address MSB (see Table 14-3) to differentiate between external and internal access. If the
address MSB is 0, then the access is to the internal chip address space; if the address MSB is 1,
the access is to the external address space. See Figure 14-4 and Table 14-3 for more information.
