IA186ES/IA188ES
8-Bit/16-Bit Microcontrollers
Table 67. In-Service Register (Master Mode)
5.1.47 INSERV (02ch) (Slave Mode)
This read-only register results in the status of interrupt request bits being presented to the
interrupt controller. The status of these bits is available when this register is read. This register
is read-only.
When an internal interrupt request (D1/I6, D0/I5, TMR2, TMR1, and TMR0) occurs, the
respective bit is set to 1. The internally generated interrupt acknowledge resets these bits. The
REQST register contains 0000h on reset (see Table 68).

Reserved
Bits [15–11]—Reserved.
Bit [10]—SP0 Serial Port 0 Interrupt Request → This is the Serial Port 0 interrupt state.
Bit [9]—SP1 Serial Port 1 Interrupt Request → This is the Serial Port 1 interrupt state.
Bits [8–4]—I [4–0] Interrupt Requests → When any of these bits is set to 1, it indicates
that the relevant interrupt has a pending interrupt.
Bit [3]—D1/I6 DMA Channel 1/Interrupt 6 Request → When set to 1, it indicates that
either the DMA channel 1 or int6 has a pending interrupt.
Bit [2]—D0/I5 DMA Channel 0/Interrupt 5 Request → When set to 1 it indicates that
either the DMA channel 0 or int5 has a pending interrupt.
Bit [1]—Reserved.
Bit [0]—TMR Timer Interrupt Request → This is the timer interrupt state and is the
logical OR of the timer interrupt requests. When set to 1, it indicates that the timer
control unit has a pending interrupt.
Bits [15–6]—Reserved.
Bit [5]—TMR2 Timer2 Interrupt In Service → Timer2 is being serviced when this bit is
set to 1.
