SDIF PullUp

In case of boot mode using SDIF port, internal PullUp

resistor is used (SDCMD0, SDAT0[3:0] / SDCMD1,

SDAT1[3:0]). So, external PullUp resistor is not required on

board.

QSCS PullUp

In case of boot mode using QSCS, PullUp of

GPIO03(QSCS) is active by the hard reset. After GPIO2E

is set to high, GPIO03 set to QSCS and PullUp set to

inactive.

In case of Hi−z boot, PullUp is forced to inactive.

GPIO2F

During boot, GPIO2F is used as GPIO and indicates boot

status and error occurrence by output of Low/High

When errors occur during boot sequences, for example

writing of IPL2, GPIO2F reports the sort of error. GPIO0F

can indicate the status of USB connection and the

completion of USB file transfer. And Delete Mode,

completion of Erase, and status of Erase can be reported by

sequence of Low/High

For more detail about the behavior of ports used during

boot, refer to the document LC823450 Series IPL

specification.
