1.1. S5PV210 Pin Information
Definitions
Available Usage(AU)
- G/E/W : GPIO & EINT & Wake up source
- G/E : GPIO & EINT
- G : GPIO
- D : Dedicated signal
- I : Internally connected to MCP and ball out
- I(x) : Internally connected to MCP and No ball out
RET @ Power down
- No_Ret: this signal doesn’t have a retention function in power down mode
- Ret_IO : this signal has a retention function in power down mode and released by setting Enable_GPIO bit
(others[31])
- Ret_IO (sleep) : this signal has a retention function in only sleep mode and released by setting Enable_GPIO bit
(others[31])
- Ret_CF : this signal has a retention function in power down mode and released by setting Enable_CF_IO bit
(others[30])
- Ret_MMC : this signal has a retention function in power down mode and released by setting Enable_ MMC_IO
bit (others[29])
- Ret_UART : this signal has a retention function in power down mode and released by setting
Enable_GPIO_UART_IO bit (others[28]) => Only Uart2, 3
- Ret_Auto : this signal has a retention in power down mode and released automatically after wakeup.
note) Need to more attention when this kinds of signals are used for GPIO,.
Because these signals move to default signal level after wakeup until S/W set to the level.
