11.8.5 16-Bit Timer 3 Capture Mode
The 16-bit Capture mode is selected by control register as shown in Figure 11.33.
The 16-bit capture mode is the same operation as 8-bit capture mode, except that the timer register uses 16 bits.
The 16-bit timer 3 capture mode is set by T3MS, T4MS
as ‘1’
. The clock source is selected from T3CK[2:0] and
16BIT bit must be set to
‘1’. Timer 3 is LSB 8-bit, the timer 4 is MSB 8-bit.
