Due to differences in internal ROM and layout pattern, flash memory version and masked ROM version
have varying electrical characteristics such as attributes, performance margins, noise endurance capac-
ity, and noise radiation. When switching to masked ROM version, administer system evaluation tests
equal to those held on the flash memory version.
I/O pins may not be placed in high-impedance states until internal voltage stabilizes, when power is
turned on in boot mode. Follow the procedure below to turn on power in boot mode.
1) Apply an "L" signal to the RESET and the CNV
2) Wait a minimum of 2ms after V
3) Apply an "H" signal to the CNV
4) Apply an "H" signal to the RESET pin (reset exited)
