Function
The test mode read enable signal (TRDB) is set
low during FREEDM-32P256 register read
accesses during production test (PMCTEST set
high). The FREEDM-32P256 drives the test
data bus (TDAT[15:0]) with the contents of the
addressed register while TRDB is low. TRDB
replaces RD[22] when PMCTEST is set high.
The test mode write enable signal (TWRB) is set
low during FREEDM-32P256 register write
accesses during production test (PMCTEST set
high). The contents of the test data bus
(TDAT[15:0]) are clocked into the addressed
register on the rising edge of TWRB. TWRB
replaces RD[23] when PMCTEST is set high.
The bi-directional test mode data bus
(TDAT[15:0]) carries data read from or written to
FREEDM-32P256 registers during production
test. TDAT[15:0] replace TD[31:16] when
PMCTEST is set high.
