1.5. Reset and Power-up
RL508 is reset by power on reset (POR), and the internal registers are reset to their default values. Upon POR asserting
from low to high, RL508 will leave out reset state.
Power-up can be set by CSR0_ENABLE and CSR0_DISABLE defined in register 06h. When RL508 is reset,
CSR0_ENABLE and CSR0_DISABLE are set to default 0. To enable RL508 into power-up mode setting
CSR0_ENABLE = 1 and CSR0_DISABLE = 0 and the following chip programming can be performed.
1.6. Initialization Sequence
The initialization sequence can be referenced in Figure 2.
1.6.1. To initialize the device
1. Supply voltage to VDD.
2. Wait 50ms then write 0x96AA to address 0 to power on the device.
3. Wait 100ms then provide RCLK
4..Set CSR0_ENABLE bit high and CSR0_DISABLE bit low to power up device. Normal software operation
should not be performed until the completion of power-up time defined in Figure 2.
1.6.2. To power down the device
1. Set CSR0_DISABLE to 1.
2. Wait 10ms before turn off RCLK.
3. Write 0x16AA to address 0 to power down the device. See Figure 3..
