In standard serial I/O mode 1, software commands, addresses and data are input and output between the
MCU and peripheral units (serial programer, etc.) using 4-wire clock-synchronized serial I/O (UART1).
Standard serial I/O mode 1 is engaged by releasing the reset with the P6
In reception, software commands, addresses and program data are synchronized with the rise of the trans-
fer clock that is input to the CLK
read data and status are synchronized with the fall of the transfer clock, and output from the TxD
The TxD
When busy, such as during transmission, reception, erasing or program execution, the RTS
"H" level. Accordingly, always start the next transfer after the RST
Also, data and status registers in memory can be read after inputting software commands. Status, such as
the operating state of the flash memory or whether a program or erase operation ended successfully or not,
can be checked by reading the status register. Here following are explained software commands, status
registers, etc.
