-// VALUES TAKEN FROM EM4x function: SendForward
-// START_GAP = 440; (55*8) cycles at 125Khz (8us = 1cycle)
-// WRITE_GAP = 128; (16*8)
-// WRITE_1 = 256 32*8; (32*8)
-
-// These timings work for 4469/4269/4305 (with the 55*8 above)
-// WRITE_0 = 23*8 , 9*8 SpinDelayUs(23*8);
-
-// Sam7s has several timers, we will use the source TIMER_CLOCK1 (aka AT91C_TC_CLKS_TIMER_DIV1_CLOCK)
-// TIMER_CLOCK1 = MCK/2, MCK is running at 48 MHz, Timer is running at 48/2 = 24 MHz
-// Hitag units (T0) have duration of 8 microseconds (us), which is 1/125000 per second (carrier)
-// T0 = TIMER_CLOCK1 / 125000 = 192
-// 1 Cycle = 8 microseconds(us) == 1 field clock
