Description
Host Bus Sub-Mode
This field determines which of three Host Bus 16 sub-modes to use.
Sub-mode use is determined by the connected external peripheral. See
Table 10-6 on page 471 for information on how this bit field affects the
operation of the EPI signals.
Value Description
0x0 ADMUX – AD[15:0]
Data and Address are muxed.
0x1 ADNONMUX – D[15:0]
Data and address are separate. This mode is not practical in
HB16 mode for normal peripherals because there are generally
not enough address bits available.
0x2 Continuous Read - D[15:0]
This mode is the same as ADNONMUX, but uses address switch
for multiple reads instead of OEn strobing. This mode is not
practical in HB16 mode for normal SRAMs because there are
generally not enough address bits available.
0x3 XFIFO – D[15:0]
This mode adds XFIFO controls with sense of XFIFO full and
XFIFO empty. This mode uses no address or ALE.
