NOTES:
1.If the PM07 bit in the PM0 register is set to "1" (BCLK not output), connect this pin to VCC via a resistor. (pulled high).
2.The ports P11 to P14 are only in the 128-pin version. When not using all of the P11 to p14 pins may be left open by setting
the PU37 bit in the PUR3 register to "0" (P11 to P14 unusable), without causing any problem.
