... OTP/ROM low pin count DESCRIPTION The Philips 83C751/87C751 offers the advantages of the 80C51 architecture in a small package and at low cost. The 8XC751 Microcontroller is fabricated with Philips high-density CMOS technology. Philips epitaxial substrate minimizes CMOS latch-up sensitivity. ...

... SFR is not used. There is also only one counter/timer, so there is no need for the TL1 and TH1 SFRs found on the 80C51. These have been replaced on the 83C751 by RTL and RTH, the counter/timer reload registers. Table 3 shows the special function registers, their locations, and reset values. ...

... I2CFG). I/O Port Latches (P0, P1, P3) The port latches function the same as those on the 80C51. Since there is no port 2 on the 83C751, the P2 latch is not used. Port 0 on the 83C751 has only 3 bits, so only 3 bits of the P0 SFR have a useful function. ...

... INT1 is level sensitive. These flags are functionally identical to the corresponding 80C51 flags, except that there is only one timer on the 83C751 and the flags are therefore combined into one register. Note that the positions of the IE0/IT0 and IE1/IT1 bits are transposed from the positions used in the standard 80C51 TCON register ...

... When this counter is running, it will carry out after 1020 to 1023 machine cycles have elapsed since a change on SCL. A carry out causes a hardware reset of the 83C751 I interface and generates an interrupt if the timer I interrupt is enabled. In cases where the bus hangup is due to a lack of software response by this 83C751, the reset releases SCL and allows I operation among other devices to continue ...
