*1 Dependent on program ("1.5 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
