UPD75P3036 NEC, UPD75P3036 Datasheet - Page 23

• Manufacturer Part Number: UPD75P3036
• Description: 4-BIT SINGLE-CHIP MICROCONTROLLER
• Manufacturer: NEC

(3) Description of symbols used in addressing area
Remarks 1. MB indicates access-enabled memory banks.
(4) Description of machine cycles
S indicates the number of machine cycles required for skipping of skip-specified instructions. The value of S varies as
shown below.
One machine cycle equals one cycle (= t
*10
*11
*1
*2
*3
*4
*5
*6
*7
*8
*9
• No skip ..................................................................... S = 0
• Skipped instruction is 1-byte or 2-byte instruction .... S = 1
• Skipped instruction is 3-byte instruction
Note 3-byte instructions: BR !addr, BRA !addr1, CALL !addr, CALLA !addr1
Caution The GETI instruction is skipped for one machine cycle.
