The IA186ES and IA188ES have a WDT and three 16-bit programmable timers. Timer0 and
timer1 each has an input and output connected to external pins that permits it to count or time
events as well as produce variable duty-cycle waveforms or non-repetitive waveforms. These
same timers are used to measure the high- and low-pulse widths of the Pulse Width Demodulator
on the pwd pin.
Because timer2 does not have external connections, it is confined to internal functions such as
real-time coding, time-delay applications, a prescaler for timer0 and timer1, or to synchronize
DMA transfers.
The Peripheral Control Block contains eleven 16-bit registers to control the programmable
timers. Each timer-count register holds the present value of its associated timer and may be read
from or written to whether the timer is in operation or not. The microcontroller increments the
value of the timer-count register when a timer event takes place.
Not available in slave mode.
An ESC opcode causes a trap.
Instruction execution generates interrupts.
Performed in the same manner as for the 8086 and 8088.
Because only one IRQ is generated for the three timers, they share priority level with other sources. The
These interrupt types are programmable in slave mode.
