EMU0 and EMU1
Warm-up counter
an external oscillator. As a result a time equivalent to the warm-up time elapses between
input of the release request and output of the system clock.
Programmable pull-up resistance
set for use as input ports. When the ports are set for use as output ports, they cannot be
turned on/off by a program.
Consequently Read-Modify-write instructions are prohibited.
Watchdog timer
watchdog timer is not to be used, disable it.
AD converter
reduce power consumption. When STOP mode is used, disable the resistor using the
program before the HALT instruction is executed.
CPU (micro DMA)

this case, an interrupt request is kept on hold internally)
status can be released without difficulty. The priority of this interrupt is compared with
that of the interrupt kept on hold internally, and the interrupt with higher priority is
handled first followed by the other interrupt.
This pin is connected to the VCC or the VSS pin. Do not alter the level when the pin is
Open pins.
The warm-up counter operates when STOP mode is released, even if the system is using
The programmable pull-up resistor can be turned on/off by a program when the ports are
The data registers (e.g., Px) are used to turn the pull-up/pull-down resistors on/off.
The watchdog timer starts operation immediately after a Reset is released. When the
The string resistor between the VREFH and VREFL pins can be cut by a program so as to
Only the LDC cr, r and LDC r, cr instructions can be used to access the control registers
The value of an undefined bit in an SFR is undefined when read.
Please execute the POP SR instruction during DI condition.
Usually, interrupts can release all halts status. However, the interrupts (INT0 to INT3,
