P89CV51RB2/RC2/RD2
80C51 with 1 kB RAM, SPI
6.10 Security bits
The security bits protect against software piracy and prevent the contents of the ash from
being read by unauthorized parties in Parallel programmer mode and ISP mode. Since the
end application might need to erase pages and read from the code memory, the security
bits have no effect in IAP mode. However, the security bits’ programmed/erased state may
be read using IAP function calls allowing the end-user code to limit access, if desired. The
security bits and their effects are shown in Table 40.
Note: On this device, MOVC instructions executed from external code memory are
prevented from fetching code bytes from internal code memory.
6.11 Interrupt priority and polling sequence
The device supports eight interrupt sources under a four-level priority scheme. Table 41
summarizes the polling sequence of the supported interrupts. Note that the SPI serial
interface and the UART share the same interrupt vector; see Figure 25.
Table 40.
Security bit functions
Security bit
Description
1
Write protect. When programmed, prohibits further erasing or
programming, except to program other security bits or a chip erase.
2
Read protect. When programmed, inhibits reading of user code memory.
3
External execution inhibit. When programmed, prevents any execution of
instructions from external code memory.
