4.3.12. SCITCER[0](+0xc0 to 0xfc)

SCITCER is the test clock enable register and is a virtual register that is selected for address offsets from 0xc0 to 0xfc. In registered clock mode, a test clock enable is produced each time this register is accessed. Reads return zeros and write data is ignored. Table 4.13 shows bit assignments for SCITCER.

BitNameTypeDescription
[0]SCITCERRead

When in registered clock mode (refer to SCITCR [16] (+0x80)), a test clock enable is produced only when this register is accessed (read or write).

A read will return zeros.

Write data is ignored.

SCITCER has a multiple word space in the register address map to allow for the generation of multiple test clock enable pulses.
