63 / 158 page ![]() eKTF6708 8-Bit Microcontroller IC Product Specification (V1.2) 03.12.2020 53 (This specification is subject to change without prior notice) 6.1.100 Bank 1 R44: FLKR (Flash Key Register for Table write use) Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 FLK[7] FLK[6] FLK[5] FLK[4] FLK[3] FLK[2] FLK[1] FLK[0] R/W R/W R/W R/W R/W R/W R/W R/W This FLASHKEY register is used by table write IAP mode operation. The IAP enable signal is generated when a specific value is written into this register, e.g., 0xB4. The register is designed to make sure that IAP operation occurs for flash update. Written into register value 0XC5. The register is designed to make sure that IAP lock. 6.1.101 Bank 1 R45: TBPTL (Table Point Low Register) Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 TB7 TB6 TB5 TB4 TB3 TB2 TB1 TB0 R/W R/W R/W R/W R/W R/W R/W R/W Bits 7~0 (TB7~TB0): Table Point Address Bits 7~0. 6.1.102 Bank 1 R46: TBPTH (Table Point High Register) Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 HLB - - TB12 TB11 TB10 TB9 TB8 R/W - - R/W R/W R/W R/W R/W Bit 7 (HLB): Obtain MLB or LSB at machine code of ROM or Data area. 0: the address of read byte value is Bit7 ~Bit0 1: the address of read byte value is Bit15~Bit8 Bits 6~5: unused bit, set to 0 all the time Bits 4~0 (TB12~TB8): Table point Address Bits 12~8. 6.1.103 Bank 1 R47: STKMON (Stack Pointer) Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 STOV - - - STL3 STL2 STL1 STL0 R - - - R R R R Bit 7 (STOV): Stack pointer overflow indicator bit. Read only. Bits 4~0 (STL3~0): Stack pointer number. Read only. 6.1.104 Bank 1 R48: PCH (Program Counter High) Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 - - - - PC11 PC10 PC9 PC8 - - - - R/W R/W R/W R/W Bits 7~4: Not used.
