14.6.1.2 Prescaler Control for TCR2
MC68HC16Y3/916Y3
USER’S MANUAL
T2CLK
DIV8 CLK
PIN
Timer count register 2 (TCR2), like TCR1, is clocked from the output of a prescaler.
The T2CG (TCR2 clock/gate control) bit and the T2CSL (TCR2 counter clock edge)
bit in TPUMCR determine T2CR2 pin functions. Refer to Table 14-2.
The function of the T2CG bit is shown in Figure 14-3.
