TMP86FS49BUG
Note 1: Always set RETM to “0” when transiting from NORMAL mode to STOP mode. Always set RETM to “1” when transiting
from SLOW mode to STOP mode.
Note 2: When STOP mode is released with RESET pin input, a return is made to NORMAL1 regardless of the RETM contents.
Note 3: fc: High-frequency clock [Hz], fs: Low-frequency clock [Hz], *; Don’t care
Note 4: Bits 1 and 0 in SYSCR1 are read as undefined data when a read instruction is executed.
Note 5: As the hardware becomes STOP mode under OUTEN = “0”, input value is fixed to “0”; therefore it may cause external
interrupt request on account of falling edge.
Note 6: When the key-on wakeup is used, RELM should be set to "1".
Note 7: Port P20 is used as STOP pin. Therefore, when stop mode is started, OUTEN does not affect to P20, and P20 becomes
High-Z mode.
Note 8: The warmig-up time should be set correctly for using oscillator.
Note 1: A reset is applied if both XEN and XTEN are cleared to “0”, XEN is cleared to “0” when SYSCK = “0”, or XTEN is cleared
to “0” when SYSCK = “1”.
Note 2: *: Don’t care, TG: Timing generator, *; Don’t care
Note 3: Bits 3, 1 and 0 in SYSCR2 are always read as undefined value.
Note 4: Do not set IDLE and TGHALT to “1” simultaneously.
Note 5: Because returning from IDLE0/SLEEP0 to NORMAL1/SLOW1 is executed by the asynchronous internal clock, the period
of IDLE0/SLEEP0 mode might be shorter than the period setting by TBTCR<TBTCK>.
Note 6: When IDLE1/2 or SLEEP1/2 mode is released, IDLE is automatically cleared to “0”.
Note 7: When IDLE0 or SLEEP0 mode is released, TGHALT is automatically cleared to “0”.
Note 8: Before setting TGHALT to “1”, be sure to stop peripherals. If peripherals are not stopped, the interrupt latch of peripherals
may be set after IDLE0 or SLEEP0 mode is released.
