9 / 91 page  CY7C63310, CY7C638xx Document Number: 38-08035 Rev. *Q Page 9 of 91 CPU Registers The CPU registers in enCoRe II devices are in two banks with 256 registers in each bank. Bit[4]/XI/O bit in the CPU Flags register must be set/cleared to select between the two register banks Table 2 on page 9 Flags Register The Flags Register is set or reset only with logical instruction. Table 2. CPU Flags Register (CPU_F) [R/W] Bit # 7 6 5 4 3 2 1 0 Field Reserved XIO Super Carry Zero Global IE Read/Write – – – R/W R RW RW RW Default 00000010 Bit [7:5]: Reserved Bit 4: XIO Set by the user to select between the register banks 0 = Bank 0 1 = Bank 1 Bit 3: Super Indicates whether the CPU is executing user code or Supervisor Code. (This code cannot be accessed directly by the user.) 0 = User Code 1 = Supervisor Code Bit 2: Carry Set by the CPU to indicate whether there has been a carry in the previous logical/arithmetic operation. 0 = No Carry 1 = Carry Bit 1: Zero Set by the CPU to indicate whether there has been a zero result in the previous logical/arithmetic operation. 0 = Not Equal to Zero 1 = Equal to Zero Bit 0: Global IE Determines whether all interrupts are enabled or disabled 0 = Disabled 1 = Enabled Note CPU_F register is only readable with the explicit register address 0xF7. The OR F, expr and AND F, expr instructions must be used to set and clear the CPU_F bits. Table 3. CPU Accumulator Register (CPU_A) Bit # 7 6 5 4 3 2 1 0 Field CPU Accumulator [7:0] Read/Write –––––––– Default 00000000 Bit [7:0]: CPU Accumulator [7:0] 8-bit data value holds the result of any logical/arithmetic instruction that uses a source addressing mode |
