2. Operational Description
2.2 System Clock Controller
TMP86CH09NG
2.2.4.4 SLOW mode
SLOW mode is controlled by the system control register 2 (SYSCR2).
The following is the methods to switch the mode with the warm-up counter.
(1) Switching from NORMAL2 mode to SLOW1 mode
First, set SYSCR2<SYSCK> to switch the main system clock to the low-frequency clock for
SLOW2 mode. Next, clear SYSCR2<XEN> to turn off high-frequency oscillation.
Note: The high-frequency clock can be continued oscillation in order to return to NORMAL2 mode from
SLOW mode quickly. Always turn off oscillation of high-frequency clock when switching from
SLOW mode to stop mode.
Example 1 :Switching from NORMAL2 mode to SLOW1 mode.
SET
(SYSCR2). 5
; SYSCR2<SYSCK>
← 1
(Switches the main system clock to the low-frequency
clock for SLOW2)
CLR
(SYSCR2). 7
; SYSCR2<XEN>
← 0
(Turns off high-frequency oscillation)
Example 2 :Switching to the SLOW1 mode after low-frequency clock has stabilized.
SET
