respectively. When host requests are enabled, the host request pins operate as shown in Figure
6-3.
Table 6-5 shows the operation of the
test these ICR bits to determine the interrupt source.
Table 6-6 shows the operation of the transmit request (
with dual host requests enabled.

6.4.5 Endian Modes
The Host Little Endian bit in the host-side Interface Control Register (ICR[5] = HLEND) allows
the host to access the HI08 data registers in Big Endian or Little Endian mode. In Little Endian
mode (HLEND = 1), a host transfer occurs as shown in Figure 6-4.
