P6OUTCUT
This pin functions as an input pin for INT4. Also, this pin
functions as an input pin for a forcibly-cut-off signal in the
motor drive waveform output mode.
[Functions]
This pin has the function to forcibly place port P6 pins in
the input mode (port-output-cutoff function). Also, this pin
functions as an input pin for INT4, and as an input pin for
the port-output-cutoff function in the motor drive wave-
form output mode.

The internal ROM is allocated to addresses 800016
through FFFF16, and its address space is 32 Kbytes.
(Line 5)
The internal ROM and RAM are allocated as shown in
Figures 1 (1) through (3).
(Line 5)
The internal RAM is allocated to addresses C0016
through FFF16, and its address space is 1 Kbyte. In
addition to storing data, the RAM is used as a stack
during a subroutine call, or interrupts.
