Note:
1. When LCD Bypass mode is set (MIFPCON[3]=1) in sleep mode, GPISLPCON and GPIPUDSLP cannot
control I port. Because in this case I port IO cells are controlled by Host I/F block(Modem I/F block) and
signals from K, L, M port IO cells. For more information, please refer to figure 10-3.
Preliminary product information describe products that are in development,
for which full characterization data and associated errata are not yet available.
