9.3 Programming Guidelines

When configuring the TIC10024-Q1, it is critical to follow the programming guideline summarized below (see Table 9-2) to ensure proper behavior of the device:

Table 9-2 TIC10024-Q1 Programming Guidelines

Category	Programming Requirement
Clean Current Polling (if CCP_INx = 1 in the CCP_CFG1 register)	At least one input has to be enabled: IN_EN_x = 1 in the IN_EN register
Wetting current auto-scaling (if WC_CFG1 [22:21] != 2b’11)	The wetting current auto-scaling feature is only activated in the continuous mode: POLL_EN = 0 ⁽¹⁾ The wetting current auto-scaling only applies to 10mA or 15mA wetting currents: WC_INx bits = 3’b100, 3’b101, 3’b110, or 3’b111 in the WC_CFG0 and WC_CFG1 registers.⁽¹⁾
Continuous mode Polling mode	t_{POLL_TIME} and t_{POLL_ACT_TIME} settings have to meet the below requirement: t_{POLL_TIM}_E ≥ 1.3 × [ t_{POLL_ACT_TIME} + n × 24 μs + 10 μs]⁽²⁾ n: the number of enabled channels configured in register IN_EN t_{POLL_TIME}: timing setting configured in CONFIG[4:1] t_{POLL_ACT_TIME}: timing setting configured in CONFIG[8:5]

Programming Requirement

Clean Current Polling (if CCP_INx = 1 in the CCP_CFG1 register)

At least one input has to be enabled: IN_EN_x = 1 in the IN_EN register

Wetting current auto-scaling (if WC_CFG1 [22:21] != 2b’11)

The wetting current auto-scaling feature is only activated in the continuous mode: POLL_EN = 0 ⁽¹⁾
The wetting current auto-scaling only applies to 10mA or 15mA wetting currents: WC_INx bits = 3’b100, 3’b101, 3’b110, or 3’b111 in the WC_CFG0 and WC_CFG1 registers.⁽¹⁾

Continuous mode

Polling mode

t_{POLL_TIME} and t_{POLL_ACT_TIME} settings have to meet the below requirement: t_{POLL_TIM}_E ≥ 1.3 × [ t_{POLL_ACT_TIME} + n × 24 μs + 10 μs]⁽²⁾

n: the number of enabled channels configured in register IN_EN
t_{POLL_TIME}: timing setting configured in CONFIG[4:1]
t_{POLL_ACT_TIME}: timing setting configured in CONFIG[8:5]

(1) These are soft requirements to take advantage of the wetting current auto-scaling feature. The feature takes no effect otherwise.

(2) If CCP is enabled, add tCCP_TRAN +tCCP_TIME, where tCCP_TIME is the timing setting configured in CCP_CFG0[6:4]
