STOP Mode Setting
When STOP Instruction Is Executed While CPU Is Operating on Main System Clock
Item
When CPU Is Operating on
Internal High-Speed
Oscillation Clock (fRH)
When CPU Is Operating on
X1 Clock (fX)
When CPU Is Operating on
External Main System Clock
(fEXCLK)
System clock
Clock supply to the CPU is stopped
Main system clock fRH
Stopped
fX
fEXCLK Input invalid
Subsystem clock fXT
Status before STOP mode was set is retained
fRL
Status before STOP mode was set is retained
CPU
Operation stopped
Flash memory
RAM
Status before STOP mode was set is retained
Port (latch)
16-bit timer/
event counter 00^{Note 1}
Operable only when TM52 output or TI000 is selected as the count clock
8-bit timer/event
counter
50
51
52^{Note 1}
Status before STOP mode was set is retained
Operable only when TI52 is selected as the count clock
8-bit timer
H0
Operable only when TM50 output is selected as the count clock during 8-bit timer/event
counter 50 operation
H1
Operable only when fRL, fRL/2⁷, fRL/2⁹ is selected as the count clock
H2
Operation stopped
Real-time counter
Operable only when subsystem clock is selected as the count clock
Watchdog timer
Operable. Clock supply to watchdog timer stops when “internal low-speed oscillator can be
stopped by software” is set by option byte.
Buzzer output
Operation stopped
10-bit successive approximation
type A/D converter^{Note 2}
Serial interface
UART0
UART6
Operable only when TM50 output is selected as the serial clock during 8-bit timer/event
counter 50 operation
LCD controller/driver
Operable only when subsystem clock is selected as the count clock
Manchester code generator
Operation stopped
Power-on-clear function
Operable
Low-voltage detection function
External interrupt
Notes 1. Do not start operation of these functions on the external clock input from peripheral hardware pins in the
stop mode.
2. μPD78F041x only.
