TIMERS and TIMER/COUNTERS
S3C72M5/C72M7/C72M9/P72M9 (Preliminary Spec)
16-BIT TIMER/COUNTER 1
OVERVIEW
The 16-bit timer/counter functions as one 16-bit timer/counter or two 8-bit timer/counters. When the 16-bit
timer/counter functions as one 16-bit timer/counter, it is called timer/counter 1 (TC1), and when it functions as two 8-
bit timer/counters, it is called timer/counter 1A (TC1A), and timer/counter 1B (TC1B).
When the mode register bit, TMOD1.7 is set to "1", the 16-bit timer/counter functions as one 16-bit timer/counter,
and when the mode register bit, TMOD1.7 is set to "0", the 16-bit timer/counter functions as two 8-bit
timer/counters.
The only functional differences between TC1 and TC1A are the sizes of the counter and reference value registers (16-
bit versus 8-bit).
The functional differences between TC1A and TC1B are the fact that only TC1A has the external event counter and
external signal divider function, and can generate a clock signal for the serial I/O interface.
The only functional difference between TC0 and TC1A is the fact that only TC1A can generate a clock signal, for the
serial I/O interface.
One 16-bit timer/counter mode (Timer/counter 1)
Two 8-bit timer/counters mode (Timer/counter 1A, 1B)
