CHAPTER 9 TIMER/COUNTER FUNCTION (REAL-TIME PULSE UNIT)
Remarks 1. If the A/D converter is set in the timer trigger mode, the compare register's match interrupt becomes
the A/D conversion start trigger, starting the conversion operation.
compare register's match interrupt functions as a compare register match interrupt to the CPU. In
order for a compare register match interrupt not to be issued to the CPU, disable interrupts with the
interrupt mask bits (P11MK0 to P11MK3) of the interrupt control register (P11IC0 to P11IC3).
2. If the A/D converter is set in the external trigger mode, the external trigger input becomes the A/D
converter starting trigger, starting the conversion operation.
trigger input also functions as Timer 1's capture trigger and as an external interrupt. In order for it
not to issue capture triggers or external interrupts, set Timer 1 in the compare register and disable
interrupts with the interrupt control register's interrupt mask bit.
If Timer 1 is not set in the compare register, and if interrupts are not disabled in the interrupt control
register, the following will happen.
(a) If the TUM15 register's interrupt mask bit (IMS153) is 0
It also functions as the compare register's match interrupt with respect to the CPU.
(b) If the TUM15 register's interrupt mask bit (IMS153) is 1
The A/D converter's external trigger input also functions as an external interrupt to the CPU.
