2.3 Reset Circuit
TMP86CH47IUG
2.3.2
Address trap reset
If the CPU should start looping for some cause such as noise and an attempt be made to fetch an instruction
from the on-chip RAM (when WDTCR1<ATAS> is set to “1”) or SFR area, address trap reset will be gener-
ated. The reset time is maximum 24/fc[s] (1.5
μ
s at 16.0 MHz). Then, the
RESET
pin outputs "L" level during
maximum 24/fc[s].
Note:The operating mode under address trapped is alternative of reset or interrupt. The address trap area is alter-
native.
Note 1: Address “a” is on-chip RAM (WDTCR1<ATAS> = “1”) space or SFR area.
Note 2: During reset release, reset vector “r” is read out, and an instruction at address “r” is fetched and decoded.
Note 3: Varies on account of external condition: voltage or capacitance

Watchdog timer reset
Refer to Section “Watchdog Timer”.
2.3.4
System clock reset
If the condition as follows is detected, the system clock reset occurs automatically to prevent dead lock of the
CPU. (The oscillation is continued without stopping.)
- In case of clearing SYSCR2<XEN> and SYSCR2<XTEN> simultaneously to
“

”
.
- In case of clearing SYSCR2<XEN> to
“

, when the SYSCR2<SYSCK> is
“

”
.
- In case of clearing SYSCR2<XTEN> to
“
0
”
, when the SYSCR2<SYSCK> is
“

”
.
The reset time is maximum 24/fc (1.5
μ
s at 16.0 MHz). Then, the
RESET
pin outputs "L" level during maxi-
mum 24/fc[s] (1.5
μ
s at 16.0MHz).
