Unused. Read = 0b. Write = don’t care.
USBFAE: USB FIFO Access Enable.
0: USB FIFO RAM not available through MOVX instructions.
1: USB FIFO RAM available using MOVX instructions. The 1k of USB RAM will be mapped
in XRAM space at addresses 0x0400 to 0x07FF. The USB clock must be active and
greater than or equal to twice the SYSCLK (USBCLK > 2 x SYSCLK) to access this
area with MOVX instructions.
Unused. Read = 0b. Write = don’t care.
EMD2: EMIF Multiplex Mode Select.
0: EMIF operates in multiplexed address/data mode.
1: EMIF operates in non-multiplexed mode (separate address and data pins).
These bits control the operating mode of the External Memory Interface.
00: Internal Only: MOVX accesses on-chip XRAM only. All effective addresses alias to
on-chip memory space.
01: Split Mode without Bank Select: Accesses below the 8k boundary are directed on-chip.
Accesses above the 8k boundary are directed off-chip. 8-bit off-chip MOVX operations use
the current contents of the Address High port latches to resolve upper address byte. Note
that in order to access off-chip space, EMI0CN must be set to a page that is not contained in
the on-chip address space.
10: Split Mode with Bank Select: Accesses below the 8k boundary are directed on-chip.
Accesses above the 8k boundary are directed off-chip. 8-bit off-chip MOVX operations use
the contents of EMI0CN to determine the high-byte of the address.
11: External Only: MOVX accesses off-chip XRAM only. On-chip XRAM is not visible to the
CPU.
00: ALE high and ALE low pulse width = 1 SYSCLK cycle.
01: ALE high and ALE low pulse width = 2 SYSCLK cycles.
10: ALE high and ALE low pulse width = 3 SYSCLK cycles.
11: ALE high and ALE low pulse width = 4 SYSCLK cycles.
