NOTES:
1. The base timer operates when its count source is selected using bits BCK1 and BCK0 in the G2BCR0 register. When both the

BT2S bit in the BTSR register and the BTS bit in the G2BCR1 register are set to 0, the base timer is placed in a reset state and
the count value remains 0000h. When either the BT2S or the BTS bit is set to 1, the count starts.
