Signal for common electrode driving signal preparation (Sharp panel dedicated signal). This
signal is multiplexed with SLCDC1_D0; PA24.
LCD Data Bus—All LCD signals are driven low after reset and when LCD is off. Through GPIO,
LD[15:0] signals are multiplexed with SLCDC1_DAT[15:0], SLCDC. PA23–PA6.
Shift Clock; PA5
ATA Data Bus, [15:0] are multiplexed with
ETMTRACEPKT4–12,
FEC_MDIO,
ETMTRACEPKT13–14
SD3_D3–0;
Through GPIO also are multiplexed with SLCDC 15–0, and FEC signals; PF23, PD16–PD2.
Noisy Supply for the I/O pins. There are 16 I/O voltage pads, N
Supply for analog blocks
Quiet GND for analog blocks
GND pins for silicon internal circuitry
For Fuse
For RTC, SCC power supply
For RTC, SCC GND
