[bit15 to bit0] TC15 to TC0: Compare bits
These bits are used to set compared values of the serial timer.
These bits will be compared with the serial timer register (STMR), and when these bits match the value of
the serial timer register immediately after the serial timer register (STMR) is updated, they will set the serial
timer register to "0". Then, these bits will set the timer interrupt flag (SACSR:INT) to "1".
Notes:
⋅
When (0000) H is set to this register, the serial timer register will remain set to "0".
⋅
When "0000" H is set to this register, the timer interrupt flag (SACSR:TINT) will be fixed to "1", if the
division value of the timer operating clock (SACSR:TDIV) is set to "0000"b during timer operation.
⋅
This register can be changed only when the serial timer is disabled (SACSR:TMRE="0").
