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).
