Input
Input
CHIP SELECT
"L" level enables to communicate with M66290A
WRITE STROBE
Input data is written into the register by the positive edge
RD
Input READ STROBE
Register data can be read when "L" level
INTERRUPT

Input/ USB DATA(+)
D+
Output D+ of USB. Connect the external resistor serially.
D-
USB
interface Vbus
Input/ USB DATA(-)
Output D- of USB. Connect the external resistor serially.
Input
Vbus INPUT (Built-in pull down resistor)
Connect to the Vbus of USB bus or to the 5V power supply.
Connection or shutdown of the Vbus can be detected.
TrON
TRST
TrON OUTPUT
Output Connect to the D+ pull-up resistor of 1.5kohm.
ON/OFF control of the pull-up resistor is available.
Input
TEST RESET INPUT (Built-in pull up resistor)
Reset input of JTAG. Even if the JTAG is not used, JTAG circuit must be
initialized. Input "L" level to initialize like the RST input.
TMS
JTAG
interface TCK
TEST MODE INPUT (Built-in pull up resistor)
Input
Mode set input to JTAG. If JTAG is not used, keep "H" level or open.
TEST CLOCK INPUT (Built-in pull down resistor)
Input
Clock input to JTAG. If JTAG is not used, keep "L" level or open.
TDI
Input TEST DATA INPUT (Built-in pull up resistor)
Data input to JTAG. If JTAG is not used, keep "H" level or open.
TDO
RST
Xin
Xout
Others
TEST1
TEST2
VCC
GND
TEST DATA OUTPUT
Output
Data output from JTAG. If the JTAG is not used, keep open.
Input RESET
"L" level initializes the register or the counter of M66290A.
Input OSCILLATO Generate an internal clock.
R INPUT Input or output of internal clock oscillator. When use as a crystal oscillator, connect a
OSCILLATO crystal between Xin and Xout.
Output R OUTPUT If an external clock is used, input it to Xin, and Xout must be opened.
TEST1 INPUT (Built-in pull down resistor)
Input
Input for the test. Keep "L" level or open.
TEST2 INPUT (Built-in pull down resistor)
Input
Input for the test. Keep "L" level or open.
