In newest LPCOpen v3.01, for GPIO's setting,
Why some functions have limit like : "port number (supports port 0 only)" for setting DIR,MASK, PIN, MPIN, SET, CLR, NOT in gpio_5410x.h file ?
supports port 0 only ? then how to do for port 1 ?
for example
/**
* @briefSet all GPIO raw pin states (regardless of masking)
* @parampGPIO: The base of GPIO peripheral on the chip
* @paramport: port Number (supports port 0 only) ????????????????????????????
* @paramvalue: Value to set all GPIO pin states (0..n) to
* @returnNothing
*/
__STATIC_INLINE void Chip_GPIO_SetPortValue(LPC_GPIO_T *pGPIO, uint8_t port, uint32_t value)
{
pGPIO->PIN[port] = value;
}
Where are those ROM_xxx functions ??
