@ -52,11 +52,11 @@ SAM7S has several timers, we will use the source TIMER_CLOCK1 (aka AT91C_TC_CLKS
TIMER_CLOCK1 = MCK/2, MCK is running at 48 MHz, Timer is running at 48/2 = 24 MHz
New timer implemenation in ticks.c, which is used in LFOPS.c
1us = 1.5ticks
1fc = 8us = 12ticks
1 μs = 1.5 ticks
1 fc = 8 μs = 12 ticks
Terms you find in different datasheets and how they match.
1 Cycle = 8 microseconds(us) == 1 field clock (fc)
1 Cycle = 8 microseconds (μs) == 1 field clock (fc)
Note about HITAG timing
Hitag units (T0) have duration of 8 microseconds (us), which is 1/125000 per second (carrier)
