Table 4.1 JTAG instruction codes
Instruction
Description
Code
SAMPLE/PRELOAD
Loads LSI internal status to BSR and sets data.
0010
BYPASS
Bypasses the scan path using BSR.
1111
EXTEST
Physical device connection check.
0000
CLAMP
Bypasses the scan path while maintaining output
values.
0011
HIGHZ
Sets all outputs to Hi-Z.
0100
IDCODE
Outputs the specified DEVICE_CODE.
0001
4.2.2 DEVICE_CODE
The DEVICE_CODE corresponding to an IDCODE instruction is composed of the following elements.
Table 4.2 DEVICE_CODE
Version
1
Part Number
0x0015
Manufacturer
0x0BE
The DEVICE_CODE response for an IDCODE instruction will therefore be 0001_0000000000010101_
00010111110_1.
4.2.3 Terminals Excluded from Boundary Scan
The following terminals do not include boundary scan cells and are therefore excluded from boundary
scanning in this LSI: DP_A, DM_A, DP_B, DM_B, R1_A, R1_B, XI, XO, VBUS_B, and TEST.
4.3 Reset
This LSI includes a hard reset function via the external XRESET terminal and soft reset function via register
settings.
4.3.1 Hard Reset
Start from reset status when power is turned on, then cancel the reset after confirming power on.
4.3.2 Soft Reset
All LSI circuits can be reset via software, or internal USB analog macros can be reset individually. The
ChipReset.AllReset bit is used to reset all circuits in this LSI, or the D_Reset.ResetDTM or H_Reset.ResetHTM
bits are used to reset the respective device analog macro or host analog macro. However, note that the analog
macro should be reset only in the SLEEP state.
4.4 Clock
This LSI contains an internal oscillator and feedback resistor (1 M) and supports clock generation using an
external resonator. The oscillator frequency can be set to 12 MHz or 24 MHz via the register settings.
Fig.4.2 shows a typical connection arrangement for an oscillator circuit. Cd, Cg, and Rd in the oscillator
circuit must be matched based on the resonator. Contact the resonator manufacturer to obtain circuit constants.
