21.6 IDCODE Register
MMC2107 – Rev. 2.0
MOTOROLA
An IEEE 1149.1 standard compliant JTAG identification register
(IDCODE) has been included on the MMC2107.
Bits 31–28 — Version Number (Part Revision Number)
Bits 27–22 — Design Center
Bits 21–12 — Device Number (Part Identification Number)
Bits 11–1 — JEDEC ID
Bit 0
Bit 31
Bit 23
Bit 15
This is equivalent to the lower four bits of the PRN of the chip
identification register located in the chip configuration module.
Indicates the Motorola Microcontroller Division
Bits 19-12 are equivalent to the PIN of the chip identification register
located in the chip configuration module.
Indicates the reduced JEDEC ID for Motorola. JEDEC refers to the
Joint Electron Device Engineering Council. Refer to JEDEC
publication 106-A and chapter 11 of the IEEE 1149.1 standard for
further information on this field.
Differentiates this register as the JTAG IDCODE register (as opposed
to the bypass register), according to the IEEE 1149.1 standard
