Timer 2 Registers
Timer 2 Control Register (T2C)

T48C862-R3
PWM Mode: Pulse-width modulation output on Timer 2 output pin (T2O)
Figure 48. PWM Modulation
Timer 2 has 6 control registers to configure the timer mode, the time interval, the input
clock and its output function. All registers are indirectly addressed using extended
addressing as described in section "Addressing Peripherals". The alternate functions of
the Ports BP41 or BP42 must be selected with the Port 4 control register P4CR, if one of
the Timer 2 modes require an input at T2I/BP41 or an output at T2O/BP42.
