SHINGLE-CHIP 16-BIT CMOS MICROCOMPUTER FLASH MEMORY VERSION
Auto erase command
Input command code 30
16
in the first transfer and command code
30
16
again in the second transfer. When this is done, the
M37753FFCFP and the M37753FFCHP execute an auto erase com-
mand. Auto erase is initiated at the last rising edge of the serial clock.
The BUSY pin is driven high during the auto erase operation. Auto
erase is completed when all memory contents are erased, and the
BUSY pin is pulled low.
Note:
In the auto erase operation, the M37753FFCFP and the
M37753FFCHP automatically repeat the erase and verify op-
erations internally. Therefore, erase is completed by execut-
ing the command once.
Error check command
Input command code 80
16
in the first transfer, and the
M37753FFCFP and the M37753FFCHP output error information
from the SDA pin, beginning at the next falling edge of the serial
clock. If the E0 of the 8-bit error information is 1, it indicates that a
command error has occurred. A command error means that some in-
valid commands other than commands shown in Table 4 has been
input.
When a command error occurs, the serial communication circuit sets
the corresponding flag and stops functioning to avoid an erroneous
programming or erase. When being placed in this state, the serial
communication circuit does not accept the subsequent serial clock
and data (even including an error check command). Therefore, if the
user wants to execute an error check command, temporarily drop the
V
PP
pin input to the V
PP
L level to terminate the serial input/output
mode. Then, place the M37753FFCFP and the M37753FFCHP into
the serial I/O mode back again. The serial communication circuit is
reset by this operation and is ready to accept commands. The error
flag alone is not cleared by this operation, so the user can examine
the serial communication circuit’s error conditions before reset. This
examination is done by the first execution of an error check com-
mand after the reset. The error flag is cleared when the user has ex-
ecuted the error check command. Because the error flag is
undefined immediately after power-on, always be sure to execute the
error check command.

Note:
When outputting the error flag, the SDA pin is switched for output at the first falling edge of the serial clock. The SDA pin is placed
in the floating state during the period of th
(C-E)
after the last rising edge of the serial clock (at the 8th bit).
