CHAPTER 5 TST3 PIN
5.1
Overview
In the MSM64P155, when the TST pin is set to "H" level, the 256Hz and 4Hz interrupt
sources are added.
The two added interrupt sources enable the MSM64P155 to be used as an OTP version
of the MSM64152A, MSM64153A or MSM64158A.
Table 5-1 lists the interrupt sources when TST3="H" and Figure 5-1 shows the interrupt
control equivalent circuit.

If two or more different interrupts occur at the same time, an interrupt with a smaller
interrupt start address number is serviced first.
When the TST3 pin is open or set to "L" level, the contents of interrupt sources are the
same as those of the MSM64155A.
