WAKE = PWR,RTC,Charger
PURX = Reset dari Retu Utk RAP
RSTX = untuk Mengaktifkan TAHVO
Vana,V10,VR = Supply Voltages dari RETU
Vr1 = Supply Voltage Utk VCTXO
VDRAM = Supply Voltage utk SDRAM
RFClk (38,4Mhz) = RF clock dari Retu Untuk RAP dan OMAP
Sleep Clock (32.768Mhz) = Oscilator 32.768 (Real Time Clock) ke RETU
Vcore A = Supply Voltages dari SMPS Vcore utk OMAP
SysClk (19.2Mhz) = Sistem Clock 19,2Mhz Dari RAP utk OMAP
CLK 600Mhz = Clock600Mhz Dari TAHVO untuk SMPS Vcore A
SMPS Synchronizing Clock (2,4Mhz) = SMPS Synchronizing Clock (2,4Mhz) dari RAP ke TAHVO
