ELECTRICAL CHARACTERISTICS (MSM6577L/C/D/E)
3.0 V operation •Backup flag (BUF)="0"
The input of the constant voltage circuit corresponds to the output of the voltage converter
(VSS1). (VDD=0 V, VSS1=–1.5 V, VSS2=–3.0 V (Battery Voltage), VSS3=–4.5 V, fOSC=32.768 kHz, CX=35 pF, Ta=25°C)

*1 Dependent on program ("0.75 mA typ." is under 5% duty of the MCU.)
*2 PORT0=P0.0 to P0.3, PORT1=P1.0 to P1.3, PORT2=P2.0 to P2.3
(P1.2 is shared with SCLK, P1.3 with SOUT, and P2.0 with SIN.)
*3 RESET pin can be selected by mask option (with pull-down, with pull-up or without inter-
nal resistor).
MSM6577L: System reset by a "H" level with a pull-down resistor
MSM6577C: System reset by a "H" level without a pull-down resistor
MSM6577D: System reset by a "L" level with a pull-up resistor
MSM6577E: System reset by a "L" level without a pull-up resistor
