The VC13 bit is useful w hen the VC27 bit in the VCR2 register is set to “1” (low voltage detection circuit enable).
The VC13 bit is alw ays “1” (VCC1 ≥ Vdet4) w hen the VC27 bit is set to “0” (low voltage detection circuit disable).
This register dose not change at softw are reset, w atchdog timer reset and oscillation stop detection reset.
Write to this register after setting the PRC3 bit in the PRCR register to “1” (w rite enable).
To use low voltage detection (hardw are reset 2), set the VC26 bit to “1” (reset level detection circuit enable).
VC26 bit is disabled in stop mode (the microcomputer is not reset even if the voltage input to VCC1 pin becomes
low er than Vdet3).
Where the VC13 bit in the VCR1 register and D42 bit in the D4INT register are used or the D40 bit is set to “1” (low
voltage detection interrupt enable), set the VC27 bit to “1” (low voltage detection circuit enable).
This register dose not change at softw are reset, w atchdog timer reset and oscillation stop detection reset.
The detection circuit dose not start operation until td(E-A) elapses after the VC26 bit, or VC27 bit is set to “1”.
