80C51 8-bit microcontroller family with extended memory
64KB/96KB OTP with 2KB/3KB RAM
FUNCTIONAL DESCRIPTION
The following paragraphs briefly describe the features of the P87C51Mx2. For more detailed information, please refer to the
P87C51Mx2 User Manual or the 51MX Architecture Reference.
INTERRUPTS
Table 1 summarizes the interrupt sources, flag bits, vector addresses, enable bits, priority bits, polling priority, and whether each
interrupt may wake up the CPU from Power Down mode.

1. S0STAT.5 = 0 selects combined Serial Port 0 Tx and Rx interrupt; S0STAT.5 = 1 selects Serial Port 0 Rx interrupt only (and
TX interrupt will be different, see Note 3 below).
2. S1STAT.5 = 0 selects combined Serial Port 1 Tx and Rx interrupt; S1STAT.5 = 1 selects Serial Port 1 Rx interrupt only (and
TX interrupt will be different, see Note 4 below).
3. This interrupt is used as Serial Port 0 Tx interrupt if and only if S0STAT.5 = 1, and is disabled otherwise.
4. This interrupt is used as Serial Port 1 Tx interrupt if and only if S1STAT.5 = 1, and is disabled otherwise.
5. If S0STAT.0 = 1, the following Serial Port 0 additional flag bits can cause this interrupt: FE_0, BR_0, OE_0.
6. If S1STAT.0 = 1, the following Serial Port 1 additional flag bits can cause this interrupt: FE_1, BR_1, OE_1.
