Mode 3
In mode 3, Timer 0 operates as two 8-bit counters, and Timer 1 stops counting and holds
its value. As shown in Figure 20 Timer 0 – Mode 3, TL0 is configured as an 8-bit
counter controlled by the normal Timer 0 control bits. TL0 can count either CPU clock
cycles (divided by 4 or by 12) or high-to-low transitions on t0, as determined by the C/T
bit. The GATE function can be used to give counter enable control to the INT0_N
signal.

TH0 functions as an independent 8-bit counter. However, TH0 can count only CPU
clock cycles (divided by 4 or by 12). The Timer 1 control and flag bits (TR1 and TF1)
are used as the control and flag bits for TH0.
When Timer 0 is in mode 3, Timer 1 has limited usage because Timer 0 uses the Timer
1 control bit (TR1) and interrupt flag (TF1). Timer 1 can still be used for baud rate
generation and the Timer 1 count values are still available in the TL1 and TH1
registers.Control of Timer 1 when Timer 0 is in mode 3 is through the Timer 1 mode
bits. To turn Timer 1 on, set Timer 1 to mode 0, 1, or 2. To turn Timer 1 off, set it to
mode 3. The Timer 1 C/T bit and T1M bit are still available to Timer 1. Therefore,
Timer 1 can count CPU_clk/4, CPU_clk/12, or high-to-low transitions on the t1 pin. The
Timer 1 GATE function is also available when Timer 0 is in mode 3.
18.8.2
Timer Rate Control
The default timer clock scheme for the nRF9E5 timers is twelve CPU clock cycles per
increment, the same as in the standard 8051. However, in the nRF9E5, the instruction
cycle is four clock cycles.
Using the default rate (twelve clocks per timer increment) allows existing application
code with real-time dependencies, such as baud rate, to operate properly. However,
applications that require fast timing can set the timers to increment every four clock
cycles by setting bits in the Clock Control register (CKCON) at SFR location 0x8E,
described in Table 67 CKCON Register – SFR 0x.
The CKCON bits that control the timer clock rates are:

5
Timer 2
4
Timer 1
3
Timer 0
When a CKCON register bit is set to 1, the associated counter increments at four-clock
intervals. When a CKCON bit is cleared, the associated counter increments at twelve-
clock intervals. The timer controls are independent of each other. The default setting for
