BITS DESCRIPTIONS
[31:11] RESERVED -
[10] ETOR2
TOR2 interrupt enable bit
When 24 bit time-out counter decrease to zero, it will set TO2 flag to
high. If we set ETOR2 to high, then the 24 bit time-out counters will
interrupt CPU to indicate that the time-out count is reached.
[9] ETOR1
TOR1 interrupt enable bit
When 16 bit time-out counter decrease to zero, it will set TO1 flag to
high. If we set ETOR1 to high, then the 16 bit time-out counters will
interrupt CPU to indicate that the time-out count is reached.
[8] ETOR0
TOR0 interrupt enable bit
When 8 bit time-out counter decrease to zero, it will set TO0 flag to high.
If we set ETOR0 to high, then the 8 bit time-out counters will interrupt
CPU to indicate that the time-out count is reached.
[7] PWRDN
Smart card POWER DOWN bit
PWRDN is used when the Smartcard controller needs to be powered
down. Powering down must be done whenever the controller needs to
switch between class A and B. When this bit is a ‘1’, it will deactivate all
contacts to the Smartcard except for SCRST_L which will be discussed
later.
When the Smartcard is removed, the H/W will also set the POWER
DOWN bit.
[6] Interface
Smart card different interface bit
Interface is used for controlling the different power control device
signals. When ‘1’, the controller will direct a power control pin is active
high. When ‘0’, a power control pin is active low to meet different power
control interface.
[5:4] RESERVED Reserved for future
[3] ESCPTI
Smart card present toggle interrupt enable bit
A rising/falling edge of SCPSNT signal triggers an interrupt if this bit is
set to "1".
0 = SCPSNT toggle interrupt is disabled.
1 = SCPSNT toggle interrupt is enabled.
[2] ESCSRI
Enable SCSR interrupt bit
An ESCSRI means interrupt enable bit for SCSR-related events such as
silent byte detected error, no stop bit error, parity bit error or overrun
error. Any SCSR-related event as described above will trigger an
interrupt if this bit is set to "1".
0 = SCSR-related event interrupt is disabled.
1 = SCSR-related event interrupt is enabled.
