(1) Internal state at reset
Table 6 shows port state at reset, and Figure 19 shows internal
state at reset (they are retained after system is released from
reset).
The contents of timers, registers, flags and RAM except shown
in Figure 19 are undefined, so set the initial value to them.
Program counter (PC) ..............................................................
Address 0 in page 0 is set to program counter.
Power down flag (P) .................................................................
Timer 1 underflow flag (T1F) ...................................................
Timer control register V1 ..........................................................
Carrier wave selection register C ............................................
Pull-down control register PU0 ................................................
Logic operation selection register LO ......................................
Most significant ROM code reference enable flag (URS)
Carry flag (CY) .........................................................................
Register A .................................................................................
Register B .................................................................................
Stack pointer (SP) ....................................................................

State at reset
“H” output
Input port (Pull-down transistor ON)
Input circuit OFF (Pull-down transistor OFF)
State after system is released from reset
High impedance state
Input circuit OFF (Pull-down transistor OFF)
Input port (Pull-down transistor ON)
Input port (Pull-down transistor OFF)
Note: The contents of all output latch is initialized to “0.”
VOLTAGE DROP DETECTION CIRCUIT
The built-in drop detection circuit is designed to detect a drop in
voltage at operating and to reset the microcomputer if the supply
voltage drops below the specified value (Typ. 1.50 V) or less.

Reset voltage
Internal reset signal
Microcomputer starts operation
after f(XIN) is counted to 16384 times.
The voltage drop detection circuit is stopped and power
dissipation is reduced at the RAM back-up mode, when the
functions except the RAM and pull-down control register (PU0)
are initialized.
