add support of modbus master ascii rename base dir name of master and slave example to be mb_slave, mb_master to avoid conflict with sdio/slave example test add Kconfig option to enable ASCII and RTU mode separately update ASCII options + remove cast for errors added baudrate for examples into Kconfig updated magic numbers for timer timeout put ascii private definitions into one file

This option places Modbus timer IRQ handler into IRAM.

This allows to avoid delays related to processing of non-IRAM-safe interrupts
|

during a flash write operation (NVS updating a value, or some other
|
||
flash API which has to perform an read/write operation and disable CPU cache).
|
||
This option has dependency with the UART_ISR_IN_IRAM option which places UART interrupt
|
||
handler into IRAM to prevent delays related to processing of UART events.
