Capturing a 16-bit or 48-bit value from the SMT Time Tag Count Register(s)
When capturing Time Tag count, the 16-bit value in SMT Time Tag Count register 0x003A is copied into Time Tag Utility
Register 0x003D. If configured for 48-bit time stamp operation, count bits 47-17 and count bits 31-16 in SMT Time Tag
Count Registers 0x003C and 0x003B are simultaneously copied into Time Tag Utility Registers 0x003F and 0x003E
respectively.
13.11. SMT Bus Monitor Time Tag Match Register (0x0040)
When MT Configuration Register bits 1-0 equal 11, the Simple Message Monitor operates with 16-bit Time Tag resolu-
tion and register 0x0040 is the only Time Tag Utility register needed.
When MT Configuration Register bits 1-0 equal 01, the Simple Message Monitor operates with 48-bit Time Tag resolu-
tion and time tag matching operations require the above register plus two additional registers:
13.12. SMT Bus Monitor Time Tag Match Mid Register (0x0041)
13.13. SMT Bus Monitor Time Tag Match High Register (0x0042)
These registers are read-write and are cleared after MR pin Master Reset. When the MTTTM bit 6 is logic 1 in the
Hardware Interrupt Enable Register 0x000F, an interrupt occurs when the MT time tag count matches the value stored
in this register triplet. If the MT is configured for 16-bit time tag, Time Tag Match Register 0x0040 is compared to Time
Tag Count register 0x003A for match determination.
If configured for 48-bit time tag operation, count bits 47-17 and 31-16 in Time Tag Match Registers 0x0042 and 0x0041
are also compared to MT Time Tag Count Registers 0x003C and 0x003B for 48-bit match determination.
Please refer to the description for MTTTM bit 6 in the Hardware Interrupt Registers described in Section 9.5.
