Auto Deactivation When Card Removal
0 = Auto deactivation Disabled when hardware detected the card removal.
1 = Auto deactivation Enabled when hardware detected the card removal.
Note:
When the card is removed, hardware will stop any process and then do deactivation
sequence (if this bit is set). If this process completes, hardware will generate an interrupt
INITIF to CPU.

INITSEL
Initial Timing Selection
This fields indicates the timing of hardware initial state (activation or warm-reset or
deactivation).
Unit: SC clock
Activation: refer to SC Activation Sequence in Figure 5.17-4
Warm-reset: refer to Warm-Reset Sequence in Figure 5.17-5.
Deactivation: refer to Deactivation Sequence in Figure 5.17-6.

CNTEN2
Internal Timer2 Start Enable Bit
This bit enables Timer 2 to start counting. Software can fill in 0 to stop it and set 1 to
reload and count.
0 = Stops counting.
1 = Starts counting.
Note1:
This field is used for internal 8 bit timer when TMRSEL (SC_CTL[14:13]) = 11.
Don’t fill CNTEN2 when TMRSEL (SC_CTL[14:13]) = 00 or TMRSEL (SC_CTL[14:13]) =
01 or TMRSEL (SC_CTL[14:13]) = 10.
Note2:
If the operation mode is not in auto-reload mode (SC_TMRCTL2[26] = 0), this bit
will be auto-cleared by hardware.
Note3:
This field will be cleared by TXRST (SC_ALTCTL[0]) and RXRST
(SC_ALTCTL[1])
. So don’t fill this bit, TXRST (SC_ALTCTL[0]), and RXRST
(SC_ALTCTL[1]) at the same time.
Note4:
If SCEN (SC_CTL[0]) is not enabled, this field cannot be programmed.

CNTEN1
Internal Timer1 Start Enable Bit
This bit enables Timer 1 to start counting. Software can fill in 0 to stop it and set 1 to
reload and count.
0 = Stops counting.
1 = Starts counting.
Note1:
This field is used for internal 8 bit timer when TMRSEL (SC_CTL[14:13]) = 10 or
TMRSEL (SC_CTL[14:13]) = 11
. Don’t fill CNTEN1 when TMRSEL (SC_CTL[14:13]) = 00
or TMRSEL (SC_CTL[14:13]) = 01.
Note2:
If the operation mode is not in auto-reload mode (SC_TMRCTL1[26] = 0), this bit
will be auto-cleared by hardware.
Note3:
This field will be cleared by TXRST (SC_ALTCTL[0]) and RXRST
(SC_ALTCTL[1])
, so don’t fill this bit, TXRST (SC_ALTCTL[0]), and RXRST
(SC_ALTCTL[1]) at the same time.
Note4:
If SCEN (SC_CTL[0]) is not enabled, this field cannot be programmed.
