NOTES :
1. If the PM07 bit in the PM0 register is set to “1” (BCLK not output), connect this pin to VCC2 via a resistor
(pulled high).
2. When not using all of the P11 to P14, 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.
