EMVSIMx_PCSR field descriptions (continued)
Field Description
25
SPDIF
Smart Card Presence Detect Interrupt Flag
Status flag to indicate that an insertion or removal of a Smart Card has been detected on port. Can create
an interrupt to the MCU if SPDIM is low and/or initiate the auto power down sequence if SAPD bit is '1'.
Write a '1' to this bit to clear.
0 No insertion or removal of Smart Card detected on Port (default)
1 Insertion or removal of Smart Card detected on Port
24
SPDIM
Smart Card Presence Detect Interrupt Mask
Interrupt mask for the presence detect interrupt flag (SPDIF).
0 SIM presence detect interrupt is enabled
1 SIM presence detect interrupt is masked (default)
23–8
Reserved
This field is reserved.
This read-only field is reserved and always has the value 0.
7
SPD
Auto Power Down Control
Writing a '1' to this location will start the autopower down sequence provided the auto power down feature
is enabled by writing '1' to SAPD bit of this register. The SPD bit will autoclear when power down is
complete.
0 No effect (default)
1 Start Auto Powerdown or Power Down is in progress
6
Reserved
This field is reserved.
This read-only field is reserved and always has the value 0.
5
SCSP
Smart Card Clock Stop Polarity
Used to control the polarity of the idle EMV SIM clock when the clock is disabled by SCEN.
0 Clock is logic 0 when stopped by SCEN
1 Clock is logic 1 when stopped by SCEN
4
SCEN
Clock Enable for Smart Card
Used to enable/disable the clock to the Smart Card. It can be forced low by hardware during the auto
power down sequence.
0 Smart Card Clock Disabled
1 Smart Card Clock Enabled
3
SRST
Reset to Smart Card
Used to control state of reset line to the Smart Card. It can be forced low by hardware during the auto
power down sequence. Smart Card reset signals are active low.
0 Smart Card Reset is asserted (default)
1 Smart Card Reset is de-asserted
2
VCCENP
VCC Enable Polarity Control
Used to control the polarity of the SVEN output pad via the SVCC_EN bit. When set to '1', this bit will
invert the value of SVCC_EN bit of this register and output to SVEN output pad of device.
