Table 192. XMCFG Register
Name
XMCFG
XMCFG is set to 1 to enable external memory access. This must
be set to 1 before any port pins function as external memory
access pins. The port pins must also be individually enabled via
the GPxCON MMR.
Table 193. XMxCON Registers
Name
XM0CON
XM1CON
XM2CON
XM3CON
XMxCON are the control registers for each memory region.
They allow the enabling/disabling of a memory region and
control the data bus width of the memory region.

Description
Selects data bus width. Set by user to select a 16-bit data
bus. Cleared by user to select an 8-bit data bus.
Enables memory region. Set by user to enable the memory
region. Cleared by user to disable the memory region.

Figure 71, Figure 72, Figure 73, and Figure 74 show the timing
for a read cycle, a read cycle with address hold and bus turn
cycles, a write cycle with address and write hold cycles, and a
write cycle with wait sates, respectively.
Reserved.
Description
Enable byte write strobe. This bit is used only for two,
8-bit memory devices sharing the same memory region.
Set by the user to gate the A0 output with the WS
output. This allows byte write capability without using
BHE and BLE signals. Cleared by user to use BHE and BLE
signals.
Number of wait states on the address latch enable STROBE.
Extra address hold time. Set by user to disable extra hold
time. Cleared by user to enable one clock cycle of hold
on the address in read and write.
Extra bus transition time on read. Set by user to disable
extra bus transition time. Cleared by user to enable one
extra clock before and after the read strobe (RS).
Extra bus transition time on write. Set by user to disable
extra bus transition time. Cleared by user to enable one
extra clock before and after the write strobe (WS).
Number of write wait states. Select the number of wait
states added to the length of the WS pulse. 0x0 is 1 clock;
0xF is 16 clock cycles (default value).
Number of read wait states. Select the number of wait
states added to the length of the RS pulse. 0x0 is 1 clock;
0xF is 16 clock cycles (default value).
