Standard serial I/O mode 1
Example Circuit Application
In standard serial I/O mode 1, software commands, addresses, and data are input and output between the MCU and a
serial programmer using 4-wire clock-synchronized serial I/O (UART1). Standard serial I/O mode 1 is initiated by
releasing the reset with the P6
In reception, the software commands, addresses, and program data are synchronized with the rise of the transfer clock
(input to the CLK1 pin) and input to the MCU on the RxD1 pin.
In transmission, the read data and status are synchronized with the fall of the transfer clock, and output from the TxD1
pin. The TxD1 pin is a CMOS output. Transfer is in 8-bit units with LSB first.
When busy, such as during transmission, reception, erasing, or program execution, the RTS1 (BUSY) pin is at a "H"
level. Accordingly, always start the next transfer after the RST1 (BUSY) pin is at a "L" level.
Figure 1.160 shows a circuit application for the standard serial I/O mode 1. Control pins will vary according to peripheral
unit (programmer), therefore check the peripheral unit (programmer) manual for more information.
