ATRTO.15 ATRTO.14 ATRTO.13 ATRTO.12 ATRTO.11 ATRTO.10 ATRTO.9 ATRTO.8
These registers (ATRLsB and ATRLsB) form the ATR timeout (ATRTO [15:0]) parameter. Time in ETU
between the leading edge of the first character and leading edge of the last character of the ATR
response. Timer is enabled when the RCVATR is set and starts when leading edge of the first start bit is
received and disabled when the RCVATR is cleared. An ATR timeout is generated if this time is
exceeded.
TS Timeout Register (STSTO): 0xFE21

The TS timeout is the time in ETU between the de-assertion of smart card reset and the leading edge of
the TS character in the ATR (when DETTS is set). The timer is started when smart card reset is
de-asserted. An ATR timeout is generated if this time is exceeded (MUTE card).

RLen.0
Table 107: The RLength Register
Time in ETUs that the hardware delays the de-assertion of RST. If set to zero and RSTCRD = 0, the
hardware adds no extra delay and the hardware will release RST after VCCOK is asserted during
power-up. If set to one, it will delay the release of RST by the time in this register. When the firmware
sets the RSTCRD bit, the hardware will assert reset (RST = 0 on pin). When firmware clears the bit, the
hardware will release RST after the delay specified in Rlen. If firmware sets the RSTCRD bit prior to
instructing the power to be applied to the smart card, the hardware will not release RST after power-up
until RLen after the firmware clears the RSTCRD bit. This provides a means to power up the smart card
and hold it in reset until the firmware wants to release the RST to the selected smart card. Works with
the selected smart card interface.
