a. ASC0 TX/RX data becomes smartcard TX/RX data when the ASC module is used in
smartcard mode.
b. Output function between PIO or smartcard module clock generator alternate function and
clock generator module frequency synthesizer clock is selected by bit 28 in the interconnect
register CONFIG_CONTROL_A (SMCARDA_DSSSMCLK_NOT_PIOBIT3). If the DSS
smartcard mode is selected (bit 28 = 1), this overrides the normal PIO or PIO alternate
function output.
c. When ASC0 is used in nonsmartcard mode, the smartcard direction signal becomes an active
low ASC TX output enable signal. The signals are in fact the same, that is, SC0_DIR = 0
means smartcard TX is active.

Bit 7 YC[0] (SC1_DETECT)
a. ASC1 TX/RX data becomes smartcard TX/RX data when the ASC module is used in
smartcard mode.
b. Output function between PIO or smartcard module clock generator alternate function and
clock generator module frequency synthesizer clock is selected by bit 29 in the interconnect
register CONFIG_CONTROL_A (SMCARDB_DSSSMCLK_NOT_PIOBIT3). If the DSS
smartcard mode is selected (bit 29 = 1) this overrides the normal PIO or PIO alternate function
output.
c. When ASC1 is used in nonsmartcard mode the smartcard direction signal becomes an active
low ASC TX output enable signal. The signals are in fact the same, that is, SC1_DIR = 0
means smartcard TX is active.
