5. If a pin with pull-up function is SAMPLEed with pull-up function enabled, the corresponding
IN register is set to 1. In this case, the corresponding Control register must be cleared to 0.
6. If a pin with open-drain function is SAMPLEed while its open-drain function is enabled and
while the corresponding OUT register is set to 1, the corresponding Control register is cleared
to 0 (the pin status is Hi-Z). If the pin is SAMPLEed while the corresponding OUT register is
cleared to 0, the corresponding Control register is set to 1 (the pin status is 0).
7. If EXTEST, CLAMP, or HIGHZ state is entered, this LSI enters guarded mode such as
hardware standby mode (RES = STBY = 0). Before entering normal operating mode from
EXTEST, CLAMP, or HIGHZ state, specify RES, STBY, FWE, and MD2 to MD0 pin to the
designated mode.
8. The EMLE pin must be cleared to 0. When the pin is set to 1, this chip functions as High-
performance user debugging interface (H-UDI).
