CHAPTER 7 INTERRUPT
●
Extended intelligent I/O service (EI
2
OS) enable bit (ISE)
If this bit is "1" when an interrupt request is generated, EI
2
OS is activated. If this bit is "0" at when an
interrupt request is generated, the interrupt sequence is activated. When the EI
2
OS termination condition is
met (when the S1 and S0 bits are not 00
B
), the ISE bit is cleared. If the corresponding peripheral function
does not have the EI
2
OS function, the ISE bit must be set to "0" by software. The ISE bit is initialized to
"0" by a reset.
●
Extended intelligent I/O service (EI
2
OS) channel selection bits (ICS3 to ICS0)
These write-only bits specify the EI
2
OS channel. The EI
2
OS descriptor address is determined based on the
value set here. The ICS bit is initialized to 0000
B
by a reset.
Table 7.3-3 shows the correspondence between the EI
2
OS channel selection bits and descriptor addresses.
