• Configure the General Purpose Counter as needed and select desired clock source
(GPCNT0/1_CLKSEL in the CLKCFG register)
• Enable Receiver by setting RCV_EN bit to 1 in CTRL register
• Receiver will enter Initial Character Detection mode if ICM bit is set or enter normal
receive mode if ICM bit is not set
• Enable LRC or CRC as desired
21.6.1.3 Configuring Transmitter
The following is a list of configurations that need to be performed (after the "Configuring
EMV SIM" step) in order to configure the EMV SIM transmitter for operation:
• Select desired re-transmission threshold for NACKed characters in TX_THD register
• This is the threshold at which the TNTE flag will be set by using the
TNACK_THD[3:0] bits
• Configure the desired Guard Time between the characters transmitted by writing to
the GETU[7:0] bits in TX_GETU register
• Configure the desired data threshold in TX_THD register.
• Enable necessary interrupts by clearing respective bits in the INT_MASK register
• Configure the General Purpose Counter as needed and select desired clock source
(GPCNT0/1_CLKSEL in the CLKCFG register)
• Enable Transmitter by setting the XMT_EN in the CTRL register
• Enable LRC & CRC as desired
• Program bytes to be transmitted into the Tx FIFO. If DMA is enabled, DMA request
will get asserted automatically.
NOTE
Tx FIFO can be written to after the transmitter is enabled
(XMT_EN = 1). Writing to Tx FIFO while transmitter is
disabled will not be successful and write access will be ignored.
NOTE
The Transmit and Receive operations are mutually exclusive
and should not be enabled together.
