CHAPTER 3
DIFFERENCES BETWEEN IE-75001-R AND TARGET DEVICES WHEN CONNECTING THE IE-75001-R
(ALL TARGET DEVICES COMMON VERSION)
3.5 Operation Using Main System Clock or Subsystem Clock
Main system clock oscillation stop (SCC.3 = 1)
The following are differences when the main system clock’s oscillation is stopped.
After switching to subsystem clock oscillation, the clock supplied to the peripheral hardware differs until the main
system clock’s oscillation is stopped.
Main system clock
Basic interval timer operation
Emulation
Does not stop
Operable via divided clock of X1
input (32 kHz x1, x2, x16)
Target Device
Stops
Stops
Supplied clock
Emulation
32 kHz x1, x2, x16
Target Device
4.19 MHz divided clock
As shown above, the emulation operates differently from the target device, and the following caution points should
be noted.
(1) Basic interval timer operation
Before switching to 32 kHz (SCC.0 = 1), set the BT interrupt to disabled mode. When the clock returns to
the main system clock (SCC.0 = 0), be sure to use the start command to clear the interrupt request flag and
counter before using the BT.
(2) Peripheral hardware operation
Before switching to 32 kHz (SCC.0 = 1), set the peripheral hardware for internal clock operation to interrupt
disabled mode or operation stop mode.
(3) When using a target device subsystem clock with a frequency other than f
XT
= 32.768 kHz, connect a (4.19
x f
XT
/32.768) MHz resonator to SX2.
f
XT
: clock to be used
