GENERAL PURPOSE INPUT/ OUTPUT

This chapter describes the General Purpose Input/ Output (GPIO).

2.1 OVERVIEW

S5PC110 includes 237 multi-functional input/ output port pins and 142 memory port pins. There are 34 general
port groups and 2 memory port groups as listed below:
•
GPA0: 8 in/out port - 2xUART with flow control
•
GPA1: 4 in/out port - 2xUART without flow control or 1xUART with flow control
•
GPB: 8 in/out port - 2x SPI
•
GPC0: 5 in/out port - I2S, PCM, AC97
•
GPC1: 5 in/out port - I2S, SPDIF, LCD_FRM
•
GPD0: 4 in/out port - PWM
•
GPD1: 6 in/out port - 3xI2C, PWM, IEM
•
GPE0,1: 13 in/out port - Camera I/F
•
GPF0,1,2,3: 30 in/out port - LCD I/F
•
GPG0,1,2,3: 28 in/out port - 4xMMC channel (Channel 0 and 2 support 4-bit and 8-bit mode, but channel 1,
and channel 3 support only 4-bit mode)
