/**
* @brief ESP8266's IBus(instruction bus) only can read data of word type by 4 bytes align,
* so if users' code read a bytes or half word from IBus, an load/store exception will occure.
*
* The exception function will read the word by align and transform it to be the right
* data that users' code want to read.
*
* CPU read data from IRAM or flash by IBus. And "const" type value or string will locate at flash by default.
* So users' code read "const" type data whose type is byte or half word should lead to exception,
* and the exception operation is so slow.
*
* For example:
*
* static const char s_output[] = "123456789";
*
* char get_byte(int index)
* {
* return s_output(index);
* }
*
* By above way, reading data may be not by 4 bytes align and word type.
*
* For this reason, we add the following function to read byte or half word without leading to exception. Firstly the function reads
* a word and then transform it to be the right data that users' code want to read. Users can modify above code to be following:
*
* static const char s_output[] = "123456789";
*
* char get_byte(int index)
* {
* return ESP_IBUS_GET_U8_DATA(index, s_output);
* }
