12.3
12.3.1
This LSI supports both big endian, in which the 0 address is the most significant byte in the byte
data, and little endian, in which the 0 address is the least significant byte. This switchover is
designated by an external pin (MD5 pin) at the time of a power-on reset. After a power-on reset,
big endian is engaged when MD5 is low; little endian is engaged when MD5 is high.
Three data bus widths are available for ordinary memory (byte, word, longword) and two data bus
widths (word and long word) for synchronous DRAM. For the PCMCIA interface, choose from
byte and word. This means data alignment is done by matching the device's data width and endian.
The access unit must also be matched to the device's bus width. This also means that when
longword data is read from a byte-width device, the read operation must happen 4 times. In this
LSI, data alignment and conversion of data length is performed automatically between the
respective interfaces.
Tables 12.6 to 12.11 show the relationship between endian, device data width, and access unit.
