CHAPTER 1: OUTLINE
(8) Output specification of other special output terminals
The following special output terminals are shared with the output (R) terminals or the I/O (P)
terminals. Consequently, the output specification (complementary output or N-channel open drain
output) of the shared terminal applies to the special output.
Special output signal
Shared port
XBZ, BZ, TOUT, FOUT
Output ports R00–R03
XRMUTE, XTMUTE, HDO, HFO
Output ports R10–R13
Serial interface input/output
I/O ports P10–P13
CL, FR
I/O ports P22, P23
(9) Output specification of the DP terminal
Either complementary output or N-channel open drain output can be selected as the output specifica-
tion for the DP (dial pulse output) terminal.
Refer to Section 4.14.2, "Mask option", for details.
(10) External voltage detection of SVD circuit
External voltage (SVD terminal–VSS terminal) detection can be selected in addition to supply voltage
(VDD terminal–VSS terminal) detection. The SVD terminal is used to input the external voltage to be
detected.
Refer to Section 4.13.2, "Mask option", for details.
(11) Tone duration time selection (DTS) for DTMF circuit
It can through DTS control resister to select 94 msec or 47 msec for tome duration time, when this
mask option is selected as "use". Otherwise, the tone duration time will be fixed at 94 msec.
Refer to section 4.14.2 "Mask option" for details.
<Mask Option List>
The following is the option list for the S1C63567.
Multiple selections are available in each option item as indicated in the option list. Using "Chapter 4
Peripheral Circuits and Operation" as reference, select the spcifications that meet the target system and
check the appropriate box. Be sure to record the spcifications for unused functions too, according to the
instructions provied. Refer to the "S5U1C63000A Manual" for the winfog.
