When the TSTOP bit in the TRBCR register is set to 1, the TRBPRE register is set to FFh.
The values of registers TRBPR and TRBSC are reloaded to the counter alternately and counted.
The count value can be read out by reading the TRBPR register even w hen the secondary period is being counted.
When the TSTOP bit in the TRBCR register is set to 1, the TRBSC register is set to FFh.
(1) Write the value to the TRBSC register.
(2) Write the value to the TRBPR register. (If the value does not change, w rite the same value second time.)
The values of registers TRBPR and TRBSC are reloaded to the counter alternately and counted.
When the TSTOP bit in the TRBCR register is set to 1, the TRBPR register is set to FFh.
