2.4.2.5 RSTATE—Rx Internal State (Transparent Mode)
The RSTATE is host-initialized before enabling the channel or after a fatal error (that is,
global overrun, busy) or after a STOP Rx command.
The high byte of RSTATE defines the function code/address type and the Motorola/Intel bit.
Bit 3 (or bit 29 for the 68360) should always be set to 1. Figure 2-15 shows the RSTATE
register for transparent mode.
For the MH360, RSTATE should be initialized to 0x3900_0000 before enabling the
channel—function code 9. Table 2-14 describes the RSTATE fields for the MH360 with
boldfaced parameters to be initialized by the user.

0 = The bus format is Intel format (little-endian).
1 = The system bus is considered to be organized in Motorola format (big-endian).
Function code—This field contains the function code for the transmitter DMA channel for
data buffers in external memory (transmit buffers). Function codes are needed by the
memory controller to decode a correct memory cycle and activate the correct handshaking.
