80 / 89 page ![]() PSD834F2V 80/89 Table 52. Reset (Reset) Timing Note: 1. Reset (RESET) does not reset Flash memory Program or Erase cycles. 2. Warm reset aborts Flash memory Program or Erase cycles, and puts the device in Read mode. Table 53. VSTBYON Timing Note: 1. VSTBYON timing is measured at VCC ramp rate of 2 ms. Table 54. ISC Timing Note: 1. For non-PLD Programming, Erase or in ISC by-pass mode. 2. For Program or Erase PLD only.
