ALE pin select bit2
0 0 : No ALE
0 1 : P53/BCLK5
1 0 : P56/RAS
1 1 : P54/HLDA
Nothing is assigned.
When read, its content is indeterminate.
Notes :
1. The register should be set after the PRC1 bit in the PRCR register is set to "1".
2. This bit is available in memory expansion mode or in microprocessor mode.
3. When setting the PM11 and PM10 bits to "112" (mode 3), DRAMC cannot be used.
4. When accessing CAN-associated registers (addresses 01E016 to 024516), the PM13 bit is set to "1"
(Two waits).
5. When setting the PM15 and PM14 bits to "012" (P53/BCLK select), the CM01 and CM00 bits in the CM0
0 0 : Mode 0 (A20 to A23 for P44 to P47)
0 1 : Mode 1 (A20 for P44,
CS2 to CS0 for P45 to P47)
1 0 : Mode 2 (A20, A21 for P44, P45,
CS1, CS0 for P46, P47)
1 1 : Mode 33
