/* OpenPC TC (Timer / Clock) support code
* (C) 2006 by Harald Welte <hwelte@hmw-consulting.de>
*
- * This idea of this code is to feed the 13.56MHz carrier clock of RC632
- * into TCLK1, which is routed to XC1. Then configure TC0 to divide this
- * clock by a configurable divider.

* PICC Simulator Side:
* In order to support responding to synchronous frames (REQA/WUPA/ANTICOL),
- * we need a second Timer/Counter (TC1). This unit is reset by an external
+ * we need a second Timer/Counter (TC2). This unit is reset by an external
* event (rising edge of modulation pause PCD->PICC) connected to TIOB2, and
* counts up to a configurable number of carrier clock cycles (RA). Once the
* RA value is reached, TIOA2 will see a rising edge. This rising edge will
