IDCODE Register (IDCODE)
IDCODE is a 32-bit register. If INSTR is set to IDCODE mode, IDCODE is connected between
TDI and TDO. The HD64F2215, HD64F2215U, HD6432215A, HD6432215B, and HD6432215C
output fixed codes H’0002200F, H’0003200F, H’001B200F, and H’001C200F, respectively, from
the TDO. Serial data cannot be written to IDCODE through TDI. Table 14.3 shows the IDCODE
configuration.

BYPASS Register (BYPASS)
BYPASS is a 1-bit register. If INSTR is specified to BYPASS mode, CLAMP mode, or HIGHZ
mode, BYPASS is connected between TDI and TDO.
14.3.4
Boundary Scan Register (BSCANR)
BSCAN is a 217-bit shift register assigned on the pins to control input/output pins.
The I/O pins consists of three bits (IN, Control, OUT), input pins 1 bit (IN), and output pins 1 bit
(OUT) of shift registers. The boundary scan test based on the JTAG standard can be performed by
using instructions listed in table 14.2. Table 14.4 shows the correspondence between the LSI pins
and boundary scan registers. (In table 14.4, Control indicates the high active pin. By specifying
Control to high, the pin is driven by OUT. ) Figure 14.2 shows the boundary scan register
configuration example.
