(b) Timer counter control register (TC2)
In the CG mode, set the timer counter output enable flag (TOE1) and TC2 as shown in Figure 6-45 (for
the format of TC2, refer to Figure 6-30 Format of Timer Counter Control Register).
TOE1 is manipulated by a bit manipulation instruction. TC2 is manipulated by an 8-, 4-, or bit manipulation
instruction.
TOE1 and TC2 are cleared to 00H when the internal reset signal is asserted.
The flags shown by a solid line in the figure below are used in the CG mode.
Do not use the flags shown by a dotted line in the CG mode (clear these flags to 0).
