TYPE
FUNCTION
M[1]
141
Ipd
Mode Select Bit 1. (Internal 20k
Pulldown) Selects mode of operation of the device
(Single-Package, Cascade-Master, Cascade-Extension, or Deselect).
M[0]
142
Ipd
Mode Select Bit 0. (Internal 20k
Pulldown) Selects mode of operation of the device
(Single-Package, Cascade-Master, Cascade-Extension, or Deselect).
HIZ
143
I
Output High-Impedance Enable (Active Low). When this pin is asserted low,
internal pullup and pulldown resistors are disabled, all outputs are put into high
impedance mode, and master request inputs (
EREQ, TMREQ1, TMREQ2) are
disabled.
PTRST must also be asserted logic 0.
MGNT0
144
O
Master Grant 0 (Active Low). Asserted low when the External Test Master is the
arbitrated master.
Configuration Mode. The master is communicating with the Switch TAP Controller in the DS26900.
Transparent Mode. The master is communicating directly with the selected secondary port.
All pins are I/O in periphery JTAG mode except the
TEST, TMREQ1, TMREQ2, EREQ, M1, M0, HIZ, RST, PTRST, PTCK, PTDI, PTDO, and
PTMS pins. All outputs are rated at 8mA.
Unused inputs must be tied to logic 1 or 0 if not used and a pullup/pulldown is not present.
O = Output
I = Input
Ipu = Input with an internal pullup
Ipd = Input with an internal pulldown
P = Power
