SCDOSTS
SC Data Pin Output Status
This bit is the pin status of SCDATAOUT.
0 = SCDATAOUT pin to low.
1 = SCDATAOUT pin to high.
[11]
PWRINV
SC_PWR Pin Inverse
This bit is used for inverse the SC_PWR pin.
There are four kinds of combination for SC_PWR pin setting by PWRINV
(SC_PINCTL[11]) and PWREN (SC_PINCTL[0]). PWRINV (SC_PINCTL[11]) is bit 1 and
PWREN (SC_PINCTL[0]) is bit 0 for SC_PWR Pin as high or low voltage selection.
00 = SC_PWR Pin is 0.
01 = SC_PWR Pin is 1.
10 = SC_PWR Pin is 1.
11 = SC_PWR Pin is 0.
Note:
Software must select PWRINV (SC_PINCTL[11]) before Smart Card is enabled by
SCEN (SC_CTL[0]).

SCDOUT
SC Data Output Pin
This bit is the pin status of SCDATOUT but user can drive SCDATOUT pin to high or low
by setting this bit.
0 = Drive SCDATOUT pin to low.
1 = Drive SCDATOUT pin to high.
Note:
When SC is at activation, warm reset or deactivation mode, this bit will be changed
automatically. So don’t fill this field when SC is in these modes.

CLKKEEP
SC Clock Enable Bit
0 = SC clock generation Disabled.
1 = SC clock always keeps free running.
Note:
When operating in activation, warm reset or deactivation mode, this bit will be
changed automatically. So don’t fill this field when operating in these modes.

SCRST
SC_RST Pin Signal
This bit is the pin status of SC_RST but user can drive SC_RST pin to high or low by
setting this bit.
Write this field to drive SC_RST pin.
0 = Drive SC_RST pin to low.
1 = Drive SC_RST pin to high.
Read this field to get SC_RST pin status.
0 = SC_RST pin status is low.
1 = SC_RST pin status is high.
Note:
When operating at activation, warm reset or deactivation mode, this bit will be
changed automatically. So don’t fill this field when operating in these modes.

PWREN
SC_PWREN Pin Signal
Software can set PWREN (SC_PINCTL[0]) and PWRINV (SC_PINCTL[11]) to decide
SC_PWR pin is in high or low level.
