Manufacturer:MAXIM Description:Only the destination of the lower-order byte in the ta- ble is well-defined, the other bits of the table word are transferred to the lower portion of TBLH, and the re- maining 1-bit words are read as ²0². The Table Higher-order byte register (TBLH) is read only. The ta- ble pointer (TBLP, TBHP) is a read/write register (07H, 1FH), which indicates the table location. Before ac- cessing the table, the location must be placed in the TBLP and TBHP (If the OTP option TBHP is disabled, the value in TBHP has no effect). The TBLH is read only and cannot be restored. If the main routine and the ISR (Interrupt Service Routine) both employ the table read instruction, the contents of the TBLH in the main routine are likely to be changed by the table read instruction used in the ISR. Errors can occur. In other words, using the table read instruction in the main rou- tine and the ISR simultaneously should be avoided. However, if the table read instruction has to be applied in both the main routine and the ISR, the interrupt should be disabled prior to the table read instruction. It will not be enabled until the TBLH has been backed up. All table related instructions require two cycles to complete the operation. These areas may function as normal program memory depending on the require- ments. Once TBHP is enabled, the instruction ²TABRDC [m]² reads the ROM data as defined by TBLP and TBHP value. Otherwise, the ROM code option TBHP is dis- abled, the instruction ²TABRDC [m]² reads the ROM data as defined by TBLP and the current program counter bits. |
