(3) Standard Serial I/O Mode
The standard serial I/O mode inputs and outputs the software
commands, addresses and data needed to operate (read, pro-
gram, erase, etc.) the internal flash memory. This I/O is clock
synchronized serial. This mode requires a purpose-specific pe-
ripheral unit.The standard serial I/O mode is different from the
parallel I/O mode in that the CPU controls flash memory rewrite
(uses the CPU rewrite mode), rewrite data input and so forth. The
standard serial I/O mode is started by connecting “H” to the P16
(CE) pin and “H” to the P42 (SCLK) pin and “H” to the CNVSS (VPP)
pin (apply 4.5 V to 5.25 V to Vpp from an external source), and re-
leasing the reset operation. (In the ordinary microcomputer mode,
set CNVss pin to “L” level.)
This control program is written in the Boot ROM area when the
product is shipped from Renesas Technology Corp.. Accordingly,
make note of the fact that the standard serial I/O mode cannot be
used if the Boot ROM area is rewritten in parallel I/O mode. Figure
154 shows the pin connections for the standard serial I/O mode.
In standard serial I/O mode, serial data I/O uses the four serial I/O
pins SCLK, RxD, TxD and SRDY (BUSY). The SCLK pin is the trans-
fer clock input pin through which an external transfer clock is
input. The TxD pin is for CMOS output. The SRDY (BUSY) pin out-
puts “L” level when ready for reception and “H” level when
reception starts.
Serial data I/O is transferred serially in 8-bit units.
In standard serial I/O mode, only the User ROM area shown in
Figure 146 can be rewritten. The Boot ROM area cannot.
In standard serial I/O mode, a 7-byte ID code is used. When there
is data in the flash memory, commands sent from the peripheral
unit (programmer) are not accepted unless the ID code matches.
Outline Performance (Standard Serial I/O
Mode)
In standard serial I/O mode, 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.
In reception, software commands, addresses and program data
are synchronized with the rise of the transfer clock that is input to
the SCLK pin, and are then input to the MCU via the RxD pin. In
transmission, the read data and status are synchronized with the
fall of the transfer clock, and output from the TxD pin.
The TxD pin is for CMOS output. Transfer is in 8-bit units with LSB
first.
When busy, such as during transmission, reception, erasing or
program execution, the SRDY (BUSY) pin is “H” level. Accordingly,
always start the next transfer after the SRDY (BUSY) pin is “L”
level.
Also, data and status registers in a memory can be read after in-
putting 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 explains software commands, status registers, etc.
