PGSEL[7:0]: XRAM Page Select Bits.
The XRAM Page Select Bits provide the high byte of the 16-bit external data memory
address when using an 8-bit MOVX command, effectively selecting a 256-byte page of
RAM.
0x00: 0x0000 to 0x00FF
0x01: 0x0100 to 0x01FF
...
0xFE: 0xFE00 to 0xFEFF
0xFF: 0xFF00 to 0xFFFF
Unused. Read = 00b. Write = don’t care.
PRTSEL: EMIF Port Select.
0: EMIF not mapped to port pins.
1: EMIF active on P4-P7.
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).
EMD1-0: EMIF Operating Mode Select.
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 4 kB boundary are directed on-chip.
Accesses above the 4 kB 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 4 kB boundary are directed on-chip.
Accesses above the 4 kB 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.
EALE1-0: ALE Pulse-Width Select Bits (only has effect when EMD2 = 0).
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.
